Summary
The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 8.5.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to delete arbitrary chat session records from the wpbot_user and wpbot_conversation tables, including chat history and conversation logs, by supplying a crafted userid value.
