| org.jenkins-ci.plugins:sidebar-link | < 2.2.2 | 2.2.2 |
| sidebar link | ≤ 2.2.1 |
Jenkins Sidebar Link Plugin allows specifying files in the userContent/ directory for use as link icons.
Sidebar Link Plugin 2.2.1 and earlier does not restrict the path of files in a method implementing form validation.
This allows attackers with Overall/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.
Sidebar Link Plugin 2.2.2 ensures that only files located within the expected userContent/ directory can be accessed.
