What is CVE-2026-82848?

The Masteriyo LMS WordPress plugin prior to version 3.4.0 is susceptible to improper access control, as it fails to verify user authorization before disclosing course enrollment records through its REST API. This vulnerability enables unauthorized users to access sensitive information, including individual learners' enrollment statuses, timestamps, and course progress data, by simply iterating through sequential record identifiers. Furthermore, it allows any enrolled user to retrieve the enrollment records of other learners, posing a significant risk to user privacy and data integrity.

Affected Version(s)

Masteriyo LMS 1.3.1 < 3.4.0

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.
