What is CVE-2025-7438?

The MasterStudy LMS Pro plugin for WordPress has a significant security vulnerability that allows attackers with at least Subscriber-level access to upload arbitrary files to the server. This flaw arises from inadequate validation of file types in the 'install_and_activate_plugin' function. While the exploitation may be challenging due to specific timing and environmental conditions, it poses a potential risk of remote code execution, necessitating prompt updates to versions preceding 4.7.9.

Affected Version(s)
