What is CVE-2026-88801?

The MDJM Event Management and Mobile Events Manager plugins for WordPress, up to version 1.7.8.7, lack proper validation of user inputs when creating roles. This weakness allows any authenticated user, including those with minimal privileges like subscribers, to inject arbitrary web scripts into the system. These scripts can execute in the context of an administrator when they access user management screens, posing significant security risks and potential data breaches.

Affected Version(s)

MDJM Event Management 0 <= 1.7.8.7

Mobile Events Manager 0 <= 1.7.8.7

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.
