{"cve":"CVE-2026-26056","nvd":{"published":"2026-02-12T22:16:06.347","modified":"2026-06-17T10:25:39.327","status":"Analyzed","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. It allows users with CR create/update permissions to execute arbitrary WASM code in the ATC controller context by injecting a malicious URL through the overrides.yoke.cd/flight annotation. The ATC controller downloads and executes the WASM module without proper URL validation, enabling attackers to create arbitrary Kubernetes resources or potentially escalate privileges to cluster-admin level.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["https://github.com/yokecd/yoke/security/advisories/GHSA-wj8p-jj64-h7ff"],"products":["yokecd:yoke"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26056","score":0.00455,"percentile":0.39473,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-wj8p-jj64-h7ff","url":"https://osv.dev/vulnerability/GHSA-wj8p-jj64-h7ff","summary":"Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection in Yoke ATC","modified":"2026-02-19T20:41:00.924491Z","packages":[{"ecosystem":"Go","name":"github.com/yokecd/yoke","purl":"pkg:golang/github.com/yokecd/yoke","ranges":["<=0.19.0"],"fixed":[]}]},{"id":"GO-2026-4493","url":"https://osv.dev/vulnerability/GO-2026-4493","summary":"Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection in Yoke ATC in github.com/yokecd/yoke","modified":"2026-02-19T20:41:00.924491Z","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).
