    Summary: Authorization bypass in Istio

    Details: In Istio 1.5.0 though 1.5.8 and Istio 1.6.0 through 1.6.7, 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. ### Specific Go Packages Affected istio.io/istio/pilot/pkg/security/authz/model/matcher
