Unlock with Pro - from £29/user/moDetect Apache Camel camel-keycloak KeycloakSecurityPolicy Authentication Bypass (CVE-2026-53913) in Elastic Security
Apache Camel's camel-keycloak component contains a KeycloakSecurityPolicy that improperly handles authentication (CWE-287), resulting in missing authentication for a critical function and a fail-open condition. Affected versions >=4.15.0 <4.18.3 and >=4.19.0 <4.21.0 allow requests to bypass Keycloak-enforced authentication checks on Camel routes, permitting unauthenticated access to protected endpoints/routes. CVSS 9.8, PoC public via GHSA-qvc3-6q9x-95pj.

Testing Methodology
Validate this detection against 3 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Simulate unauthenticated request to Keycloak-protected Camel route
Expected signal: Application/access log entry showing a request to /secured/test-endpoint with no Authorization header and an HTTP 200-series response.
- Test 2Repeated bypass attempts to trigger threshold-based alerting
Expected signal: Five sequential log entries within a 5-minute window from the same client IP hitting /admin/config without Authorization headers, each returning 2xx.
- Test 3Windows-based PowerShell simulation of unauthenticated access
Expected signal: Access log entry recording a request to /protected/data with an empty Authorization header field and a successful HTTP status code.
