CVE-2023-30851 (GCVE-0-2023-30851)

Vulnerability from cvelistv5 – Published: 2023-05-25 17:47 – Updated: 2025-01-16 19:15
VLAI?
Summary
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.
Severity ?
