The ArtiBot Free Chat Bot for WordPress WebSites plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the artibot_update function in all versions up to, and including, 1.1.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to update plugin settings.
