Vulnerability Snapshot

CVE-2026-46455 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.

Executive Summary

Insufficient Session Expiration vulnerability in Apache Camel Keycloak Component.

The camel-keycloak security helper KeycloakSecurityHelper.parseAndVerifyAccessToken builds a Keycloak TokenVerifier using withChecks(...) with only the subject-exists check and the realm-URL (issuer) check. Keycloak's TokenVerifier.withChecks(...) appends to an initially empty check list - the upstream default checks are installed only when withDefaultChecks() is called - so the built-in IS_ACTIVE predicate, which validates the token's exp (expiration) and nbf (not-before) claims, is never applied. As a result the helper verifies the token signature, subject and issuer but does not enforce the token's validity window: an access token that is expired, or not yet valid, is accepted as valid. Routes that rely on this helper to authenticate inbound requests therefore accept access tokens that are outside their intended lifetime.

This issue affects Apache Camel: from 4.18.0 before 4.18.3, from 4.19.0 before 4
