CVE-2023-2887Network attack vector

Unauthenticated access via undisclosed identity spoofing

Published May 25, 2023 · Updated May 22, 2026

Authentication bypass in CBOT Chatbot Core before 4.0.3.4 and Panel before 4.0.3.7 allows remote attackers to gain authenticated access. The published record identifies spoofing in the authentication path but does not disclose the affected endpoint, trusted identifier, or validation error that accepts attacker-controlled identity data. No credentials or user interaction are required, but public records do not identify which protected data or functions become accessible.
