Technical details

The vulnerability is a path traversal flaw in the stm_lms_import_sample_data AJAX action, which processes the stm_lms_step parameter without proper capability checks or nonce verification. Authenticated Subscriber-level users can supply directory traversal sequences (e.g., ../../../) to reference arbitrary WXR XML files on the server filesystem, causing the plugin to import and publish their contents as posts. The lack of authorization controls and input validation allows an authenticated attacker to reach files beyond the intended import directory.
