| Doc Text: |
A flaw was found in Jenkins. A remote attacker could exploit a vulnerability in the origin validation of requests made through the Command Line Interface (CLI) WebSocket endpoint. By manipulating the Host or X-Forwarded-Host HTTP headers, an attacker can perform Domain Name System (DNS) rebinding attacks. This allows bypassing the origin validation, potentially leading to unauthorized actions within the Jenkins environment.
