Foxtheme Foxtool All-in-One: Contact chat button, Custom login, Media optimize images vulnerabilities

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.

The Foxtool All-in-One: Contact chat button, Custom login, Media optimize images plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.2. This is due to missing or incorrect nonce validation on the foxtool_login_google() function. This makes it possible for unauthenticated attackers to establish an OAuth Connection via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
