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":"2026-09-15T15:17:17.11+00:00","modifiedAt":"2026-09-30T17:43:24.057+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.8,"severity":"MEDIUM"}],"references":["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","https://github.com/kumahq/kuma/pull/16777","https://github.com/kumahq/kuma/security/advisories/GHSA-wvmp-6r4v-j6cv"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-52724","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-295"],"productCriteria":[],"sourceDates":{"published":"2026-09-15T15:17:17.110","lastModified":"2026-09-30T17:43:24.057"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
