Description
The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the qsm_dashboard_delete_result function in all versions up to, and including, 10.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete quiz results.
