The plugin does not perform proper permission checks in methods implementing form validation and does not require POST requests. The severity is rated as Medium according to the CVSS scoring system (Jenkins Advisory).

This vulnerability allows attackers with Overall/Read permission to connect to an attacker-specified HTTP server using attacker-specified credentials IDs obtained through another method, potentially leading to the capture of credentials stored in Jenkins (Jenkins Advisory).

The vulnerability has been fixed in XebiaLabs XL Release Plugin version 22.0.1. The fix implements proper permission checks requiring Overall/Administer permission for the affected form validation methods and enforces POST requests. Users should upgrade to version 22.0.1 or later to address this vulnerability (Jenkins Advisory).
