Vikinger <= 1.9.32 - Authenticated (Subscriber+) Arbitrary File Deletion via vikinger_delete_activity_media_ajax Function

Vulnerability Description

The Vikinger theme for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the vikinger_delete_activity_media_ajax() function in all versions up to, and including, 1.9.32. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Note: Requires Vikinger Media plugin to be installed and active.
