CyberRota Analysis
AI-GeneratedThe vulnerability arises from insufficient enforcement of source-address restrictions in several authentication callbacks, including PasswordCallback and KeyboardInteractiveCallback, allowing unauthorized access based on client remote addresses. This oversight could lead to unauthorized users bypassing security measures, potentially compromising sensitive systems. Organizations utilizing these authentication methods should prioritize remediation to mitigate the risk of unauthorized access.
Original NVD Description
The source-address critical option in the Permissions returned by an authentication callback was only enforced for the PublicKeyCallback and VerifiedPublicKeyCallback paths, extending the fix for CVE-2026-46595. Permissions returned by the PasswordCallback, KeyboardInteractiveCallback, NoClientAuthCallback, and GSSAPIWithMICConfig.AllowLogin callbacks were not validated against the client's remote address, so a source-address restriction set by those callbacks was silently ignored. The check is now applied to the Permissions returned by any authentication callback.
