XebiaLabs XL Release Plugin 22.0.0 and earlier does not perform permission checks in methods implementing form validation.

This allows attackers with Overall/Read permission to connect to an attacker-specified HTTP server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Additionally, these form validation methods do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

XebiaLabs XL Release Plugin 22.0.1 requires POST requests and Overall/Administer permission for the affected form validation methods.
