{"id":"CVE-2026-26056","state":"PUBLISHED","title":"Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection 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. 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.","publishedAt":"2026-02-12T21:11:13.408Z","updatedAt":"2026-02-12T21:33:22.829Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","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-wj8p-jj64-h7ff"],"weaknesses":["CWE-94"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/26xxx/CVE-2026-26056.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-26056","state":"PUBLISHED","datePublished":"2026-02-12T21:11:13.408Z","dateUpdated":"2026-02-12T21:33:22.829Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-10T18:01:31.899Z"},"containers":{"cna":{"title":"Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection in Yoke ATC","descriptions":[{"lang":"en","value":"Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer.
