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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-306"],"references":["https://github.com/yokecd/yoke/security/advisories/GHSA-965m-v4cc-6334"],"products":["yokecd:yoke"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26055","score":0.00466,"percentile":0.40392,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-965m-v4cc-6334","url":"https://osv.dev/vulnerability/GHSA-965m-v4cc-6334","summary":"Unauthenticated Admission Webhook Endpoints in Yoke ATC","modified":"2026-02-19T20:56:27.572336Z","packages":[{"ecosystem":"Go","name":"github.com/yokecd/yoke","purl":"pkg:golang/github.com/yokecd/yoke","ranges":["<=0.19.0"],"fixed":[]}]},{"id":"GO-2026-4491","url":"https://osv.dev/vulnerability/GO-2026-4491","summary":"Unauthenticated Admission Webhook Endpoints in Yoke ATC in github.com/yokecd/yoke","modified":"2026-02-19T20:40:58.850921Z","packages":[{"ecosystem":"Go","name":"github.com/yokecd/yoke","purl":"pkg:golang/github.com/yokecd/yoke","ranges":["all versions"],"fixed":[]}]}],"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).
