CVE-2023-50931Network attack vector

Unencrypted notifications via configuration-page CSRF

Published Jan 9, 2024 · Updated Apr 17, 2025

Cross-site request forgery in S/Notify for Bitbucket before 2.0.1 allows attackers to alter app configuration through an administrator's session. The configuration pages accept state-changing requests triggered from attacker-controlled content in an authenticated administrator's browser. An administrator must be logged in and interact with a malicious link or website; changed settings can leave notification email unencrypted.
