CVE-2026-16773
The WPBot – AI ChatBot for Live Support, Lead Generation, AI Services plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 8.5.9 via the wpbot_send_email_transcript_free.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
