- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

## Affected

- ludwigyou WPMasterToolKit (WPMTK) – All in one plugin: through 2.13.0

## Description

The WPMasterToolKit plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 2.13.0. This is due to the plugin allowing Author-level users to create and execute arbitrary PHP code through the Code Snippets feature without proper capability checks. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute arbitrary PHP code on the server, leading to remote code execution, privilege escalation, and complete site compromise.
