Title
AsyncHttpClient: Origin credentials sent to the proxy on the plaintext CONNECT request
Summary
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 2.16.1 and 3.0.12, a request using an HTTP proxy to reach an HTTPS origin can expose preemptive origin credentials because NettyRequestFactory and NettyRequestSender.sendRequestWithNewChannel attach Authorization to the plaintext CONNECT request before the TLS tunnel exists. Basic or Digest credentials and per-connection NTLM, Kerberos, or SPNEGO tokens intended for the origin are therefore visible to the proxy and to observers on the client-to-proxy hop. The tunneled request still receives origin Authorization after the tunnel is established, while Proxy-Authorization remains on CONNECT for its intended proxy recipient. This issue is fixed in versions 2.16.1 and 3.0.12.

Title
AsyncHttpClient: SOCKS proxy credentials sent to the origin server over plaintext HTTP
Summary
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.1.0 until 2.16.1 and 3.0.12, requests using an authenticated SOCKS proxy can expose the proxy's credentials to the origin because NettyRequestFactory and NettyRequestSender attach Proxy-Authorization without confirming that the request is being sent to an HTTP proxy. With preemptive proxy authentication, the header is attached to a plaintext HTTP request, exposing credentials such as directly reversible Basic credentials to the origin. With the default non-preemptive flow, a hostile origin can return a 407 response and ProxyUnauthorized407Interceptor sends the proxy credentials through the existing SOCKS tunnel, including NTLM, Kerberos, and SPNEGO credentials. Releases before 2.1.0 lack SOCKS proxy support. This issue is fixed in versions 2.16.1 and 3.0.12.

Title
AsyncHttpClient: Client-wide realm credentials re-sent to a cross-origin redirect target
Summary
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.14.5 to 2.16.0 and from 3.0.9 to 3.0.11, a client configured with a client-wide Realm and redirect following can disclose credentials after a cross-origin redirect because the Interceptors authentication path falls back to the client configuration after redirect handling clears the per-exchange realm. If the attacker-controlled target returns 401, the client can send Basic or Digest credentials or a Negotiate or NTLM token to that origin. Per-request realms are stripped correctly, and this issue is a residual bypass of the earlier cross-origin credential-stripping fixes. This issue is fixed in versions 2.16.1 and 3.0.12.

Title
Onyx 4.6.6 Custom Tool Secret Header Disclosure via Tool Endpoints
Summary
Onyx 4.6.6 fails to properly restrict access to custom tool credentials stored in custom_headers, allowing any authenticated user to read admin-defined API keys. Attackers with basic authentication can call GET /tool/{tool_id} or GET /tool endpoints to retrieve plaintext authorization headers and third-party API credentials, then use them to directly access upstream APIs.

CVE-2026-84179 (GCVE-0-2026-84179)

Title
Apache Storm Nimbus, Apache Storm UI: Disclosure of Unredacted Merged Daemon Configuration via the Topology Page
Summary
Description
getTopologyPageInfo merged the Nimbus daemon configuration with the topology's own configuration and returned the result without redaction in the topology_conf field of TopologyPageInfo. The Storm UI copied that value verbatim into the configuration field of GET /api/v1/topology/{id} and of the corresponding metrics endpoint.
Where the cluster is configured with them, the merged map includes storm.zookeeper.auth.payload, which Storm's own documentation directs operators to keep in storm-cluster-auth.yaml under permissions that deny access from workers, together with the keystore and truststore passwords for the Thrift, Netty and ZooKeeper TLS configuration, and any plugin key whose name denotes a secret.
getTopologyPageInfo is a topology read-only operation. Under SimpleACLAuthorizer a principal listed in topology.readonly.users or topology.readonly.groups could therefore read daemon credentials that the dedicated cluster configuration API, getNimbusConf, redacts and that is gated on nimbus.users instead. The sibling operations that exist to serve configuration were masked; the topology page, which merges in strictly more daemon state, was not.
Mitigation
Upgrade to 3.1.0, where credential-bearing values are masked before any configuration is served over the Nimbus API.
Users who cannot upgrade immediately should remove any principal that is not trusted with cluster credentials from topology.readonly.users, topology.readonly.groups, topology.users and topology.groups, and should rotate the ZooKeeper authentication payload and any TLS keystore or truststore passwords that were reachable through the topology page.

Title
Apache Storm Nimbus, Apache Storm Client: Disclosure of the Topology ZooKeeper Credential to Read-Only Users and to Logs
Summary
Description
When ZooKeeper authentication is configured, Storm deliberately retains
`storm.zookeeper.topology.auth.payload` in the topology configuration, because workers need it. Nimbus then
served that configuration verbatim to any caller holding read-only topology permissions, so a user whose
only grant was the ability to view a topology received its ZooKeeper credential.
That credential is not read-only. The cluster state implementation uses write-capable ACLs for worker
heartbeats, backpressure and error state, so a recipient can forge or remove that state for the topology
concerned. It is not a write credential on assignments.
The same advisory covers the submission client, which logged the generated payload at INFO on every
submission that generated one, and the SASL handlers, which logged it at DEBUG. The credential therefore
also reached any log aggregation or support bundle collected from the cluster.
Mitigation
Upgrade to 3.1.0, where the payload is removed from the configuration served to read-only callers and is no
longer written to logs.
Users who cannot upgrade immediately should rotate `storm.zookeeper.topology.auth.payload` for existing
topologies, review retained logs and support bundles for the value, and restrict read-only topology
permissions to trusted principals.

Title
Apache Storm Nimbus, Apache Storm UI: Disclosure of Unredacted Daemon Configuration via Nimbus and the UI
Summary
Description
`getNimbusConf` returned the complete daemon configuration without redaction after only a user-level
authorization check. Where the cluster is configured with them, that response includes
`storm.zookeeper.auth.payload` and the keystore and truststore passwords for the Thrift, Netty and
ZooKeeper TLS configuration. The project masks passwords elsewhere before display, so the omission here is
inconsistent rather than intended.
The UI endpoint `/api/v1/cluster/configuration` compounded this. It carried no `@AuthNimbusOp` annotation,
and the authorization filter treated a missing annotation as "no gate required" and returned immediately, so
the endpoint applied no per-user check at all and proxied the request under the UI daemon's own principal.
Any user able to pass `ui.filter` therefore received the full configuration, including principals that
Nimbus itself would have refused.
Mitigation
Upgrade to 3.1.0, where credential-bearing values are masked before the configuration is served and where
every UI API endpoint must declare its authorization explicitly.
Users who cannot upgrade immediately should place the UI behind an authenticating reverse proxy that
restricts `/api/v1/cluster/configuration`, and should rotate the ZooKeeper authentication payload and any
TLS keystore or truststore passwords that were reachable through it.

gitoxide 0.25.4 HTTP Credential Leak via Redirect
Summary
gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects. The vulnerability occurs because credential validation checks the original URL instead of the effective URL after redirect, allowing attackers to steal authentication tokens through cross-domain redirects or HTTPS-to-HTTP downgrades.

Mitigation
Architecture and Design
Use an appropriate security mechanism to protect the credentials.
Mitigation
Architecture and Design
Make appropriate use of cryptography to protect the credentials.
Mitigation
Implementation
Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
CAPEC-102: Session Sidejacking
Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.
CAPEC-474: Signature Spoofing by Key Theft
An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
CAPEC-50: Password Recovery Exploitation
An attacker may take advantage of the application feature to help users recover their forgotten passwords in order to gain access into the system with the same privileges as the original user. Generally password recovery schemes tend to be weak and insecure.
CAPEC-509: Kerberoasting
Through the exploitation of how service accounts leverage Kerberos authentication with Service Principal Names (SPNs), the adversary obtains and subsequently cracks the hashed credentials of a service account target to exploit its privileges. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. As an authenticated user, the adversary may request Active Directory and obtain a service ticket with portions encrypted via RC4 with the private key of the authenticated account. By extracting the local ticket and saving it disk, the adversary can brute force the hashed value to reveal the target account credentials.
CAPEC-551: Modify Existing Service
When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.
CAPEC-555: Remote Services with Stolen Credentials
This pattern of attack involves an adversary that uses stolen credentials to leverage remote services such as RDP, telnet, SSH, and VNC to log into a system. Once access is gained, any number of malicious activities could be performed.
CAPEC-560: Use of Known Domain Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate credentials (e.g. userID/password) to achieve authentication and to perform authorized actions under the guise of an authenticated user or service.
CAPEC-561: Windows Admin Shares with Stolen Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate Windows administrator credentials (e.g. userID/password) to access Windows Admin Shares on a local machine or within a Windows domain.
CAPEC-600: Credential Stuffing
An adversary tries known username/password combinations against different systems, applications, or services to gain additional authenticated access. Credential Stuffing attacks rely upon the fact that many users leverage the same username/password combination for multiple systems, applications, and services.
CAPEC-644: Use of Captured Hashes (Pass The Hash)
An adversary obtains (i.e. steals or purchases) legitimate Windows domain credential hash values to access systems within the domain that leverage the Lan Man (LM) and/or NT Lan Man (NTLM) authentication protocols.
CAPEC-645: Use of Captured Tickets (Pass The Ticket)
An adversary uses stolen Kerberos tickets to access systems/resources that leverage the Kerberos authentication protocol. The Kerberos authentication protocol centers around a ticketing system which is used to request/grant access to services and to then access the requested services. An adversary can obtain any one of these tickets (e.g. Service Ticket, Ticket Granting Ticket, Silver Ticket, or Golden Ticket) to authenticate to a system/resource without needing the account's credentials. Depending on the ticket obtained, the adversary may be able to access a particular resource or generate TGTs for any account within an Active Directory Domain.
CAPEC-652: Use of Known Kerberos Credentials
An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain.
CAPEC-653: Use of Known Operating System Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate operating system credentials (e.g. userID/password) to achieve authentication and to perform authorized actions on the system, under the guise of an authenticated user or service. This applies to any Operating System.
