• CVE-2026-62284: 0.51% estimated exploitation activity in the next 30 days; percentile 43.50 (FIRST EPSS, 2026-11-10). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact The console-proxy's RemoteConfigResolver parses kubeconfig data from Kubernetes Secrets using clientcmd.RESTConfigFromKubeConfig without sanitizing the resulting rest.Config. A kubeconfig containing an exec plugin stanza (under users[].user.exec) is faithfully preserved. When rest.TransportFor later builds the HTTP transport for the upstream WebSocket connection, client-go invokes the exec plugin — spawning an arbitrary process as the osac-console-proxy service account. This allows remote code execution inside the console-proxy pod for any principal that can create or modify a Secret with the label osac.openshift.io/remote-cluster-kubeconfig: "true" in a namespace where the console-proxy has Secret read access (governed by its RoleBinding). A secondary vector exists via attacker-controlled clusters[].server, enabling server-side request forgery (SSRF) from within the proxy pod. Affected configurations: any deployment using remote or auto VM cluster mode (the default).…

# Patch Next advisory brief: CVE-2026-62284

Advisory: OSAC operator: Kubeconfig credential-plugin execution and SSRF in console proxy
IDs: CVE-2026-62284, GHSA-5w5g-j6hw-6p8f
Record: https://patchnext.com/advisories/cve-2026-62284 (revision 2, source checked 7 Nov 2026, 06:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/osac-project/osac-operator 0.0.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/osac-project/osac-operator: affected < 0.0.4; fixed in 0.0.4

## Suggested inspection (read-only)
- Go github.com/osac-project/osac-operator: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/osac-project/osac-operator.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
