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":"2026-09-15T14:50:32.257+00:00","modifiedAt":"2026-09-15T15:21:20.402+00:00","affected":[{"ecosystem":"Vendor product","name":"kuma","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kumahq\",\n                    \"product\": \"kuma\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.7.26\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.8.0, < 2.9.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.10.0, < 2.11.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.12.0, < 2.12.11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.13.0, < 2.13.7\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"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":"MEDIUM"}],"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://www.cve.org/CVERecord?id=CVE-2026-52724","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-52724","identifiers":["CVE-2026-52724"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
