Versions 1.15.0 to 1.15.15, 1.16.0 to 1.16.8, and 1.17.0 to 1.17.2, are vulnerable when using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can leave the source node without encryption due to a race condition in how traffic is processed by Cilium. This issue has been patched in versions 1.15.16, 1.16.9, and 1.17.3. There are no workarounds available for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N","score":4.0},"cwes":["CWE-362","CWE-319"],"references":["https://github.com/cilium/cilium/pull/38592","https://github.com/cilium/cilium/security/advisories/GHSA-5vxx-c285-pcq4"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-32793","score":0.00142,"percentile":0.03544,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5vxx-c285-pcq4","url":"https://osv.dev/vulnerability/GHSA-5vxx-c285-pcq4","summary":"In Cilium, packets from terminating endpoints may not be encrypted in Wireguard-enabled clusters","modified":"2026-09-10T03:50:23.531960272Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.13.0 <1.15.16"],"fixed":["1.15.16"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.16.0 <1.16.9"],"fixed":["1.16.9"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.17.0 <1.17.3"],"fixed":["1.17.3"]}]},{"id":"GO-2025-3635","url":"https://osv.dev/vulnerability/GO-2025-3635","summary":"In Cilium, packets from terminating endpoints may not be encrypted in Wireguard-enabled clusters in github.com/cilium/cilium","modified":"2026-02-04T02:52:20.037704Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.13.0 <1.15.16",">=1.16.0 <1.16.9",">=1.17.0 <1.17.3"],"fixed":["1.15.16","1.16.9","1.17.3"]}]}],"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).
