- 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.
The Forminator plugin for WordPress has a vulnerability in versions up to and including 1.27.0 that allows authenticated attackers with administrative privileges to upload arbitrary files. This vulnerability has been patched in version 1.28.0.
This vulnerability was identified by researcher István Márton. It resides in the 'forminator_allowed_mime_types' function, where insufficient blacklisting enables the upload of potentially harmful files. While the htaccess configuration of the plugin prevents remote code execution, the flaw still poses a significant risk. The potential for misuse by authenticated users with administrative access underscores the need for stringent access controls and regular security audits.
Advice for Users:
- Immediate Action: Update to the patched version 1.28.0.
- Check for Signs of Vulnerability: Monitor file uploads for unusual or unexpected files.
