The dataplane authentication token is sent over the unverified connection, allowing an on-path attacker to intercept the token, impersonate the control plane, inject a forged bootstrap configuration, and take over the proxy. Standard Kubernetes installations created by kumactl install control-plane or the official Helm chart are unaffected because the mutating admission webhook injects KUMA_CONTROL_PLANE_CA_CERT into each sidecar. This issue is fixed in versions 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":5.8,"severity":null}],"references":["https://github.com/kumahq/kuma/security/advisories/GHSA-wvmp-6r4v-j6cv","https://github.com/kumahq/kuma/pull/16777","https://github.com/kumahq/kuma/commit/2d0fb382924598f8746bc85c896f50384675940f","https://github.com/kumahq/kuma/commit/85716397ffa404234bf365da0967eca0b0fa1870","https://github.com/kumahq/kuma/commit/a256af4869ae7e0ebbc2a14dc231e04ac8df1ba3","https://github.com/kumahq/kuma/commit/bb56ae628753aaec1f7846a514ab4edc35c0b569","https://github.com/kumahq/kuma/commit/d4ae0c0151596be991897651f20c5cdf32de1980","https://github.com/kumahq/kuma/commit/eb81494c2c7a5536e55c19cdde51b02a03b51e11"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-78771","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 15, 2026, 2:50:32 PM","dateUpdated":"Sep 15, 2026, 3:21:20 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
