How to fix?

Upgrade Wolfi kubescape to version 4.0.12-r8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kubescape package and not the kubescape package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

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.
