The Foxtool All-in-One: Contact chat button, Custom login, Media optimize images plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to 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.
AnalysisAI
Missing authorization checks in the Foxtool All-in-One plugin for WordPress (all versions up to and including 2.5.3) allow any authenticated subscriber-level user to modify arbitrary subkeys of the plugin's foxtool_settings option, including the media-up3 toggle that enables site-wide SVG uploads - a change that can be chained into stored cross-site scripting through a malicious SVG file rendered by a victim. The settings modification itself is unauthenticated only in the sense that no additional user interaction is required once a low-privileged account exists; exploitation therefore matters mainly on sites with open registration or untrusted subscriber accounts. …
