Jenkins Bitbucket Branch Source Plugin prior to 746.v350d2781c184, 725.vd9f8be0fa250, 2.9.11.2, and 2.9.7.2 does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.

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

Bitbucket Branch Source Plugin 746.v350d2781c184, 725.vd9f8be0fa250, 2.9.11.2, and 2.9.7.2 requires POST requests for the affected HTTP endpoint.
