Jenkins Deployer Framework Plugin vulnerable to Path Traversal

Jenkins Deployer Framework Plugin 85.v1d1888e8c021 and earlier does not restrict the name of files in methods implementing form validation.

This allows attackers with Item/Read permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.

Deployer Framework Plugin 86.v7b_a_4a_55b_f3ec ensures that only files contained inside the expected directory can be accessed.
