CVE-2026-1832
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.
Does this matter?
Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.
