Short explanation
An improper authentication vulnerability exists in the Apache Camel Keycloak component. The issue occurs because the security processor skips issuer validation when the introspection response lacks an iss claim.
In environments meeting the required conditions, a caller that should have been rejected may be successfully authenticated and accepted.
What should be done?
- Upgrade to Apache Camel version 4.23.0
- Upgrade users on 4.18.x LTS stream to 4.18.5
- Upgrade users on 4.22.x LTS stream to 4.22.1

Show the technical text from the sources
Improper Authentication vulnerability in Apache Camel Keycloak component. This issue affects Apache Camel: from 4.15.0 before 4.18.5, from 4.19.0 before 4.22.1. The security processor validated the issuer of an introspected token only when the introspection response actually carried an iss claim. When the claim was absent the check was skipped rather than treated as a failure, so a token that the configured issuer did not mint could be accepted provided the introspection endpoint answered without naming an issuer. Reaching this requires an introspection endpoint that omits iss and accepts tokens from more than one issuer, which is not the default Keycloak arrangement, hence the low severity; where that arrangement exists the consequence is that the deployment authenticates a caller it should have rejected. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. An absent iss claim is now treated as a validation failure rather than as a reason to skip the check. For deployments that cannot upgrade immediately, ensure the introspection endpoint returns the iss claim, and that it serves exactly one issuer.
