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.

Affected configurations

• cilium cilium (< 1.11.16) • cilium cilium (>= 1.12.0 < 1.12.9) • cilium cilium (>= 1.13.0 < 1.13.2)
