How to fix?

Upgrade istio.io/istio/pilot/pkg/security/authz/model/matcher to version 1.5.9, 1.6.8 or higher.

Overview

istio.io/istio/pilot/pkg/security/authz/model/matcher is an open platform to connect, manage, and secure microservices.

Affected versions of this package are vulnerable to Improper Access Control. When users specify an AuthorizationPolicy resource with DENY actions using wildcard suffixes (e.g. *-some-suffix) for source principals or namespace fields, callers will never be denied access, bypassing the intended policy.
