Mitigations
{**Immediate action:** Configure the API gateway to require authentication and restrict `/api/compute` and `/api/jobs` to known clients only.
```yaml
# planetary-config.yaml
api:
authentication:
required: true
allowAnonymous: false
endpoints:
- path: /api/compute
allowedOrigins: ["trusted-client.internal"]
- path: /api/jobs
allowedOrigins: ["trusted-client.internal"]
```
Apply via `kubectl apply -f planetary-config.yaml` or equivalent config management.
**Verification:** Test that anonymous POST requests return `401 Unauthorized`.
**Rollback:** Set `allowAnonymous: true` if legitimate workflows break, but prioritize patching to 2.6.2 within 24โ48 hours.
**Note:** This does *not* fix the vuln, only reduces attack surface. Authenticated users can still trigger deserialization.}
