CVE-2023-24434Network attack vector

Credential theft via CSRF-enabled validation requests

Published Jan 24, 2023 · Updated Apr 2, 2025

Cross-site request forgery in Jenkins GitHub Pull Request Builder Plugin 1.42.2 and earlier allows attackers to capture stored credentials. Form-validation methods accept non-POST requests without permission checks and connect to an attacker-controlled URL using a supplied credentials ID. Exploitation requires user interaction and a valid credentials ID obtained separately, and it exposes the associated Jenkins credential to the remote server.
