The Wolfi security team deemed this advisory irrelevant for Wolfi:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kyverno-1.16 package and not the kyverno-1.16 package as distributed by Wolfi.
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.
