CVE-2025-64150Network attack vector

Credential theft via unchecked connection endpoint

Published Oct 29, 2025 · Updated Oct 29, 2025

Missing authorization in Jenkins Publish to Bitbucket Plugin 0.4 and earlier allows remote authenticated users to capture stored credentials. The HTTP endpoint accepts a caller-supplied URL and credentials ID without a permission check, then authenticates to that URL with the selected Jenkins credential. Overall/Read permission and a credential ID obtained through another method are required, and the attacker-controlled server receives the credential.
