4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
The ThriveDesk – Live Chat, AI Chatbot, Helpdesk & Knowledge Base plugin for WordPress is vulnerable to unauthorized cache deletion due to a missing capability check on the 'thrivedesk_clear_cache' AJAX action in all versions up to, and including, 2.1.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to clear the plugin's cache.
