Source record

Technical 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.

CVE / CNA vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
