CVE-2023-30851 Information

Description

Cilium is a networking observability and security solution with an eBPF-based dataplane. This issue only impacts users who have a HTTP policy that applies to multiple toEndpoints AND have an allow-all rule in place that affects only one of those endpoints. In such cases a wildcard rule will be appended to the set of HTTP rules which could cause bypass of HTTP policies. This issue has been patched in Cilium 1.11.16 1.12.9 and 1.13.2.
