Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in the Masteriyo - LMS plugin for WordPress (versions <= 2.3.1). The flaw is rooted in insufficient authorization checks when handling user-controlled keys or object identifiers. An attacker authenticated with Subscriber-level privileges can exploit this by manipulating input parameters to interact with unauthorized objects or database records.
