SCA: security update for github.com/osac-project/osac-operator (GHSA-5w5g-j6hw-6p8f)

high Tenable Self-Hosted Container Security Plugin ID 478620

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-62284)

Solution

Update the github.com/osac-project/osac-operator library and its related packages to version 0.0.4 or later.
