Description
A path traversal vulnerability exists in the MasterStudy LMS plugin for WordPress versions before 3.7.50. Authenticated users with Subscriber-level privileges can exploit this flaw by supplying directory traversal sequences in a specific AJAX parameter, allowing them to import arbitrary WXR XML files. This enables attackers to publish posts with attacker-controlled content under their identity without proper capability checks or nonce verification.
