NVD Description

Note: Versions mentioned in the description apply only to the upstream jenkins-2.516 package and not the jenkins-2.516 package as distributed by Chainguard.

Jenkins 2.442 through 2.554 (both inclusive), LTS 2.426.3 through LTS 2.541.2 (both inclusive) performs origin validation of requests made through the CLI WebSocket endpoint by computing the expected origin for comparison using the Host or X-Forwarded-Host HTTP request headers, making it vulnerable to DNS rebinding attacks that allow bypassing origin validation.
