Advisory
Source description from Wordfence Intelligence, credited to Hüseyin TINTAŞ.
The LifterLMS – WordPress LMS Plugin for eLearning plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 7.4.2 via the maybe_serve_export function. This makes it possible for authenticated attackers, with administrator or LMS manager access and above, to read the contents of arbitrary CSV files on the server, which can contain sensitive information as well as removing those files from the server.
