What is CVE-2026-48922?

The Jenkins Credentials Binding Plugin fails to properly sanitize file names for both file and zip file credentials. This vulnerability allows attackers with job access to write files to arbitrary locations on the node's filesystem. If Jenkins is configured to permit low-privileged users to modify file or zip file credentials for jobs executed on the built-in node, this can facilitate the potential for remote code execution. The risk arises when file credentials are improperly trusted without adequate checks, thus exposing systems to possible malicious activity.

Affected Version(s)
