CVE-2023-24428Network attack vector

Forced account-bound login via missing OAuth state

Published Jan 24, 2023 · Updated Apr 2, 2025

Cross-site request forgery in Jenkins Bitbucket OAuth Plugin 0.12 and earlier allows attackers to force account-bound logins. The OAuth commence-login and finish-login handlers omit generation, transport, and validation of a session-bound state value. Exploitation requires user interaction with an attacker-initiated OAuth authorization flow and binds the resulting Jenkins session to the attacker's Bitbucket account.
