NVD Description

Note: Versions mentioned in the description apply only to the upstream jenkins package and not the jenkins package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
