Advisory
Source description from Wordfence Intelligence, credited to Karthik Ramakrishnan.
The Link Library plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 7.9.5. This is due to insufficient validation of a user supplied path. This makes it possible for authenticated attackers, with contributor-level access and above, to perform actions on image files and directories outside of the intended directory.
