CVE-2024-28152: Jenkins Bitbucket Branch Source Plugin has incorrect trust policy behavior for pull requests

March 6, 2024 (updated November 7, 2024)

In Jenkins Bitbucket Branch Source Plugin 866.vdea_7dcd3008e and earlier, except 848.850.v6a_a_2a_234a_c81, when discovering pull requests from forks, the trust policy “Forks in the same account” allows changes to Jenkinsfiles from users without write access to the project when using Bitbucket Server.
