Improper Authentication Vulnerability in Apache Camel's HTTP Component

CVE-2026-66908

What is CVE-2026-66908?

Apache Camel's HTTP component exhibits an improper authentication vulnerability that affects versions 4.8.0 to 4.21.x. When JWT authentication is configured, the server fails to validate the 'iss' and 'aud' claims of incoming tokens if neither the jwtIssuer nor jwtAudience are specified, leading to a situation where any unexpired token signed by a trusted key is accepted. This oversight, arising from a workaround in the configuration, compromises the security guarantees expected by operators. Users are strongly advised to upgrade to version 4.22.0 or higher, where this issue is rectified and validation mechanisms are enforced by default.
