{"id":"CVE-2026-62284","state":"PUBLISHED","title":"OSAC operator: Kubeconfig credential-plugin execution and SSRF in console proxy","description":"OSAC operator is a Kubernetes operator. In the affected revision identified as 8220502, the `console-proxy` `RemoteConfigResolver` parses Kubernetes Secret kubeconfig data with `clientcmd.RESTConfigFromKubeConfig` without sanitizing the resulting `rest.Config`. An attacker who can create or modify a Secret labeled `osac.openshift.io/remote-cluster-kubeconfig`: \"true\" in a namespace where the proxy's RoleBinding grants Secret read access can supply `users[].user.exec`. When `rest.TransportFor` builds the HTTP transport for an upstream WebSocket connection, client-go invokes that exec credential plugin, spawning an arbitrary process as the osac-`console-proxy` service account inside the pod. Attacker-controlled `clusters[].server` also enables server-side request forgery from the proxy pod. Remote and auto VM cluster modes are affected, with auto the default; exclusively `local` mode does not read kubeconfig Secrets and is unaffected. The credential-plugin execution path is patched in commit 7e4222b; that patch does not address the described server-address SSRF path.","publishedAt":"2026-10-30T19:23:39.257Z","updatedAt":"2026-10-30T22:15:16.751Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["osac-project osac-operator"],"affected":[{"vendor":"osac-project","product":"osac-operator","versions":[{"version":"< 7e4222b","status":"affected"}]}],"references":["https://github.com/osac-project/osac-operator/security/advisories/GHSA-5w5g-j6hw-6p8f","https://github.com/osac-project/osac-operator/pull/321","https://github.com/osac-project/osac-operator/commit/7e4222b6ab465fc00606c8cfed980b226820cb1b","https://github.com/osac-project/osac-operator/commit/86466378aa3603253dca7fa2f59a2733af0dc092"],"weaknesses":["CWE-94","CWE-918"],"ingestedAt":"2026-10-30T22:26:06.415Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/62xxx/CVE-2026-62284.json","commit":"f02cde01d713f161fa6518ef321d5dace5470571","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-62284","state":"PUBLISHED","datePublished":"2026-10-30T19:23:39.257Z","dateUpdated":"2026-10-30T22:15:16.751Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-13T18:37:08.487Z"},"containers":{"cna":{"title":"OSAC operator: Kubeconfig credential-plugin execution and SSRF in console proxy","descriptions":[{"lang":"en","value":"OSAC operator is a Kubernetes operator.
