What is CVE-2026-88845?

The MasterStudy LMS WordPress plugin prior to version 3.7.50 lacks necessary capability and nonce checks during an administrative maintenance action. This oversight allows any authenticated user, including those with the lowest privilege levels like subscribers, to create published content on the website under their own account. This vulnerability emphasizes the importance of robust authentication and access controls in web applications to prevent unauthorized actions.

Affected Version(s)

MasterStudy LMS WordPress Plugin 2.3.0 < 3.7.50

Exploit Proof of Concept (PoC)
