6.6
Unrestricted Upload of File with Dangerous Type
CVE CVE-2023-6133
CVSS 6.6 (Medium)
Publicly Published November 14, 2023
Last Updated January 22, 2024
Researcher István Márton - Wordfence

Description

The Forminator plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient blacklisting on the 'forminator_allowed_mime_types' function in versions up to, and including, 1.27.0. This makes it possible for authenticated attackers with administrator-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed.
