CVE-2026-42520: Jenkins Credentials Binding Plugin has a path traversal vulnerability

April 29, 2026 (updated May 6, 2026)

Jenkins Credentials Binding Plugin versions 719.v80e905ef14eb_ and earlier do not sanitize file names for file and zip file credentials.

This allows attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem. If Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node, this can lead to remote code execution.

Credentials Binding Plugin 720.v3f6decef43ea_ sanitizes the file name provided for file and zip file credentials, preventing path traversal.
