As published by the source; long descriptions are shortened.

Improper Authentication, Missing Authentication for Critical Function, Not Failing Securely ('Failing Open') vulnerability in Apache Camel Keycloak Component. The KeycloakSecurityPolicy of camel-keycloak guards a route by running KeycloakSecurityProcessor.beforeProcess(), which performs three checks in sequence: it rejects a request that carries no access token, then - only if requiredRoles is non-empty - validates the roles, and - only if requiredPermissions is non-empty - validates the permissions. The actual cryptographic verification of the bearer access token (signature, issuer and expiry for a local JWT, or active-state and issuer for token introspection) is performed exclusively inside those role and permission checks. KeycloakSecurityPolicy defaults requiredRoles and requiredPermissions to empty - which is the documented 'Basic Setup' - so on a route configured that way the role and permission checks are skipped and the access token is therefore never verified.

# Patch Next advisory brief: CVE-2026-53913

Advisory: Apache Camel: KeycloakSecurityPolicy has Improper Authentication, Missing Authentication for Critical Function and Failing Open Vulnerabilities
IDs: CVE-2026-53913, GHSA-qvc3-6q9x-95pj
Record: https://patchnext.com/advisories/cve-2026-53913 (revision 1, source checked 26 Oct 2026, 16:54 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.camel:camel-keycloak 4.21.0, 4.18.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.camel:camel-keycloak: affected >= 4.15.0, < 4.18.3; >= 4.19.0, < 4.21.0; fixed in 4.21.0, 4.18.3

## Suggested inspection (read-only)
- Maven org.apache.camel:camel-keycloak: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.camel:camel-keycloak.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qvc3-6q9x-95pj (GitHub-reviewed advisory GHSA-qvc3-6q9x-95pj lists affected ranges: Maven org.apache.camel:camel-keycloak >=4.15.0 =4.19.0 <4.21.0)
