{"id":"CVE-2026-26055","state":"PUBLISHED","title":"Unauthenticated Admission Webhook Endpoints in Yoke ATC","description":"Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer. In 0.19.0 and earlier, a vulnerability exists in the Air Traffic Controller (ATC) component of Yoke. The ATC webhook endpoints lack proper authentication mechanisms, allowing any pod within the cluster network to directly send AdmissionReview requests to the webhook, bypassing Kubernetes API Server authentication. This enables attackers to trigger WASM module execution in the ATC controller context without proper authorization.","publishedAt":"2026-02-12T21:07:17.914Z","updatedAt":"2026-02-12T21:36:37.816Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["yokecd yoke"],"affected":[{"vendor":"yokecd","product":"yoke","versions":[{"version":"<= 0.19.0","status":"affected"}]}],"references":["https://github.com/yokecd/yoke/security/advisories/GHSA-965m-v4cc-6334"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/26xxx/CVE-2026-26055.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-26055","state":"PUBLISHED","datePublished":"2026-02-12T21:07:17.914Z","dateUpdated":"2026-02-12T21:36:37.816Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-10T18:01:31.899Z"},"containers":{"cna":{"title":"Unauthenticated Admission Webhook Endpoints in Yoke ATC","descriptions":[{"lang":"en","value":"Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer.
