Prior to versions 1.16.17, 1.17.10, and 1.18.4, CiliumNetworkPolicys which use egress.toGroups.aws.securityGroupsIds to reference AWS security group IDs that do not exist or are not attached to any network interface may unintentionally allow broader outbound access than intended by the policy authors. In such cases, the toCIDRset section of the derived policy is not generated, which means outbound traffic may be permitted to more destinations than originally intended. This issue has been patched in versions 1.16.17, 1.17.10, and 1.18.4. There are no workarounds for this issue.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":4,"severity":null}],"references":["https://github.com/cilium/cilium/security/advisories/GHSA-38pp-6gcp-rqvm","https://github.com/cilium/cilium/commit/a385856b59c8289cc7273fa3a3062bbf0ef96c97","https://github.com/cilium/cilium/releases/tag/v1.16.17","https://github.com/cilium/cilium/releases/tag/v1.17.10","https://github.com/cilium/cilium/releases/tag/v1.18.4"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-199886","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Nov 29, 2025, 12:11:26 AM","dateUpdated":"Dec 1, 2025, 7:15:21 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
