Description
When authentication is enabled on the Apache Camel embedded HTTP server or embedded management server (camel-platform-http-main) and a non-root context path such as /api or /admin is configured via camel.server.path or camel.management.path, the BasicAuthenticationConfigurer and JWTAuthenticationConfigurer classes derive the authentication path from properties.getPath() when camel.server.authenticationPath / camel.management.authenticationPath is not explicitly set. Combined with the Vert.x sub-router mounting model - the sub-router is mounted at _path_* and the authentication handler is registered inside the sub-router at the resolved path - this causes the authentication handler to match only the exact configured context path, not its subpaths. Unauthenticated requests to subpaths such as /api/_route_ or /admin/observe/info therefore reach protected business routes and management endpoints without being challenged for credentials. The /observe/info endpoint can disclose runtime metadata such as the user, working directory, home directory, process ID, JVM and operating system information.

This issue affects Apache Camel: from 4.14.1 before 4.14.6, from 4.18.0 before 4.18.2.

Users are recommended to upgrade to version 4.20.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, they are suggested to upgrade to 4.14.6. If users are on the 4.18.x LTS releases stream, they are suggested to upgrade to 4.18.2.

AI Analysis

Impact

Authentication on the Apache Camel embedded HTTP server can be bypassed when the server or management path includes a non‑root context such as "/api" or "/admin". The authentication handlers are installed only for the exact context path, so sub‑paths like "/api/_route_" or "/admin/observe/info" are not protected. This allows unauthenticated users to reach protected business routes and, for example, query the "/observe/info" endpoint to reveal runtime metadata such as the current user, working directory, JVM and operating system details.

Affected Systems

Apache Camel Platform HTTP Main versions 4.14.1 through 4.14.5, 4.18.0 and 4.18.1 are affected. Users running older releases must upgrade to the fixed releases 4.14.6, 4.18.2, or the most recent 4.20.0.

Risk and Exploitability

The CVSS score of 8.2 indicates a high severity issue, but the EPSS score is below 1 %, implying a low likelihood of exploitation at present. The vulnerability is not listed in CISA’s KEV catalog. Attackers can exploit the flaw remotely by sending HTTP requests to vulnerable sub‑paths; no local privilege escalation is required. Once authenticated or bypassed, attackers can gain unauthorized access to application logic and expose sensitive system information.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Apache Camel Platform HTTP Main to a fixed release – 4.20.0, or at least 4.14.6 for LTS 4.14.x and 4.18.2 for LTS 4.18.x.
  • Explicitly set the authentication path for server and management contexts by adding camel.server.authenticationPath=/api and camel.management.authenticationPath=/admin (or the relevant context) to ensure the authentication handler covers subpaths.
  • Verify that no unsecured subpaths remain by reviewing the routing configuration and ensuring all business routes are behind an authentication handler or by disabling the vulnerable server paths if the application does not require them.
