The School Management System for Wordpress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the homework.php file in all versions up to, and including, 93.2.0. This makes it possible for authenticated attackers, with Student-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE-2025-31100 is potentially a duplicate of this.
