What is CVE-2026-82851?

The Masteriyo LMS plugin for WordPress, prior to version 3.4.1, inherently lacks mechanisms to verify whether a user has the rightful ownership of requested records. This flaw permits users assigned the instructor role to download unrestricted content and metadata associated with any posts, including sensitive materials from other instructors' private and draft courses, leading to privacy breaches and potential data leaks.

Affected Version(s)

Masteriyo LMS 1.14.0 < 3.4.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
