Overview

github.com/cilium/cilium/pkg/policy is a package for eBPF-based Networking, Security, and Observability

Affected versions of this package are vulnerable to Access Control Bypass when HTTP policies are specified by header rules such that an HTTP policy applies to multiple toEndpoints, and there is an allow-all rule in place that affects only one of those endpoints. In such cases, a wildcard rule is appended to the set of HTTP rules.
