CVE-2022-31013Network attack vector

Unauthenticated access via unawaited token verification

Published May 31, 2022 · Updated Apr 23, 2025

Authentication bypass in Raman Chat Server 2.3.2 through versions before 2.6.0 allows remote attackers to authenticate with invalid access tokens. The access-key handler calls the asynchronous this.authProvider.verifyAccessKey function without await, so its try block returns HTTP 200 before a rejected verification promise reaches the catch block. No credentials or user interaction are required, and operations protected solely by this check accept an invalid token.
