Description

Jenkins Warnings Next Generation Plugin 8.4.4 and earlier does not perform permission checks in methods implementing form validation.

This allows attackers with Item/Read permission but without Item/Workspace or Item/Configure permission to check whether attacker-specified file patterns match workspace contents. A sequence of requests can be used to effectively list workspace contents.

Jenkins Warnings Next Generation Plugin 8.5.0 requires Item/Configure permission to validate patterns with workspace contents.

CWEs
