CVE-2023-49673Network attack vector

CSRF via GET connection test endpoint

Published Nov 29, 2023 · Updated Jun 5, 2025

Cross-site request forgery in Jenkins NeuVector Vulnerability Scanner Plugin 1.22 and earlier allows remote attackers to trigger outbound connections. The connection-test HTTP endpoint accepts non-POST requests and uses attacker-specified hostname, port, username, and password when opening the connection. Exploitation requires a logged-in Jenkins user with Overall/Read permission or a victim browser session, and can induce connections to attacker infrastructure with supplied credentials.
