Description

The Group Chat & Video Chat by AtomChat plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'atomchat_update_auth_ajax' and 'atomchat_update_layout_ajax' functions in all versions up to, and including, 1.1.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update plugin options, including critical settings such as API keys, authentication keys, and layout configurations.
