CVE-2023-41937Public exploitNetwork attack vector

Credential theft via webhook-controlled outbound request

Published Sep 6, 2023 · Updated Sep 26, 2024

SSRF in Jenkins Bitbucket Push and Pull Request Plugin 2.4.0 through 2.8.3 allows remote attackers to capture stored Bitbucket credentials. The getCommitLinks path passes webhook-controlled URLs to callClient, which sends requests carrying configured credentials in the Authorization header. The webhook endpoint is unauthenticated, but a matching job must trigger a build before the outbound request occurs.
