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.

Affected Version(s)

Apache Camel 4.8.0 < 4.22.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
