CVE-2023-37954Network attack vector

Unintended build execution via GET-enabled rebuild endpoint

Published Jul 12, 2023 · Updated Nov 6, 2024

Cross-site request forgery in Jenkins Rebuilder Plugin 320.v5a_0933a_e7d61 and earlier allows remote attackers to rebuild a previous build. A rebuild HTTP endpoint accepts a state-changing request without requiring POST, allowing a victim's authenticated browser request to start the prior build again. Exploitation requires user interaction and a session authorized to rebuild the targeted job; the bounded consequence is an unintended build execution.
