The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

istio.io/istio/pilot/pkg/security/authz/matcher is an An open platform to connect, manage, and secure microservices.
Affected versions of this package are vulnerable to Authentication Bypass. An HTTP request with a fragment in the URI path (a section in the URI that begins with a #
character) could bypass Istio’s URI path-based authorization policies. For instance, an Istio authorization policy may deny requests sent to the URI path /user/profile
. In the vulnerable versions, a request with URI path /user/profile#section1
bypasses the deny policy and routes to the backend (with the normalized URI path /user/profile%23section1
), possibly leading to a security incident.
You are impacted by this vulnerability if you use authorization policies with DENY actions and operation.paths
, or ALLOW actions and operation.notPaths
.
The fix depends on a fix in Envoy, which is associated with CVE-2021-32779.
