In the 1.15 branch prior to 1.15.8 and the 1.16 branch prior to 1.16.1, Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular, request headers are matched before request methods, when the specification describes that the request methods must be respected before headers are matched. This could result in unexpected behaviour with security This issue is fixed in Cilium v1.15.8 and v1.16.1. There is no workaround for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-436","CWE-113"],"references":["https://github.com/cilium/cilium/commit/a3510fe4a92305822aa1a5e08cb6d6c873c8699a","https://github.com/cilium/cilium/pull/34109","https://github.com/cilium/cilium/security/advisories/GHSA-qcm3-7879-xcww"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-42487","score":0.00535,"percentile":0.45183,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qcm3-7879-xcww","url":"https://osv.dev/vulnerability/GHSA-qcm3-7879-xcww","summary":"Gateway API route matching order contradicts specification","modified":"2026-09-10T03:50:18.772773817Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.1"],"fixed":["1.16.1"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.8"],"fixed":["1.15.8"]}]},{"id":"GO-2024-3071","url":"https://osv.dev/vulnerability/GO-2024-3071","summary":"Gateway API route matching order contradicts specification in github.com/cilium/cilium","modified":"2026-02-04T02:38:24.475583Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.8",">=1.16.0 <1.16.1"],"fixed":["1.15.8","1.16.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
