What is CVE-2026-92920?

The Admin3 product by CJBI contains a session management flaw where user sessions are not invalidated upon account deactivation. This allows attackers to maintain their previous authenticated status, thereby accessing resources with the user's original permissions. The vulnerability arises from the AuthInterceptor not verifying the user's account status, permitting the continued use of bearer tokens issued before the account disabling. As a result, even after an account is locked, the session remains active, leading to potential unauthorized access.

Affected Version(s)

admin3 0 <= 3.0.0

Exploit Proof of Concept (PoC)
