Until an official fix is available, restrict access to the vulnerable functionality if possible or disable the wpbot_send_email_transcript_free feature to prevent unauthorized email transcript sending. Monitor for updates from the vendor quantumcloud regarding patches or official mitigations.
Description
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. This makes it possible for unauthenticated attackers to exfiltrate full chat transcripts and associated user PII — including names, email addresses, and phone numbers — stored in the wpbot_user and wpbot_conversation tables to an attacker-controlled email address.
