This vulnerability is classified as Cross-Site Request Forgery (CSRF) (CWE-352), which allows attackers to trick authenticated users into performing unintended actions. An issue was discovered in savignano S/Notify before 2.0.1 for Bitbucket. While an administrative user is logged on, the configuration settings of S/Notify can be modified via a CSRF attack.
