Vulnerability from github – Published: 2026-04-29 15:30 – Updated: 2026-05-06 22:45

Summary

Jenkins Credentials Binding Plugin has a path traversal vulnerability

Details

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.

Severity

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
