CVE-2023-2883Network attack vector

Authentication bypass via user-controlled object key

Published May 25, 2023 · Updated May 22, 2026

Authorization bypass in CBOT Chatbot Core before 4.0.3.4 and Panel before 4.0.3.7 allows remote authenticated users to evade access checks. The published record identifies an insecure direct object reference driven by a user-controlled key, but it does not disclose the affected request, parameter, or authorization check. Low-privileged network access is required; successful exploitation permits authentication abuse and bypass, while the precise operations exposed remain undisclosed.
