Описание
File path filters in the agent-to-controller security subsystem of Jenkins 2.318 and earlier, LTS 2.303.2 and earlier do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories.
A link following vulnerability was found in Jenkins. The file path filters do not canonicalize paths allowing operations to follow symbolic links to directories they are not supposed to have access to. This may allow an attacker to read and write arbitrary files on the Jenkins controller file system.
