Summary
The Foxtool All-in-One plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.3 due to improper verification that a user is authorized to perform an action. An authenticated attacker with subscriber-level access and above can modify arbitrary subkeys of the foxtool_settings option, including enabling site-wide SVG uploads by toggling the media-up3 key, which can facilitate stored cross-site scripting via malicious SVG files.
Risk Assessment
An attacker can enable dangerous features like SVG uploads, leading to potential code injection and user session compromise.
