High
Description
The ContentStudio plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the cstu_update_post() function in all versions up to, and including, 1.3.7. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. CVE-2025-67910 is likely a duplicate of this.
