🎯 Affected products2
- Red Hat Satellite 6.19
- registry.redhat.io/satellite/iop-host-inventory-rhel9@sha256:b75188c693e2e7309c250b0c3a6dc7be5f65f581886e24da980cde7ed5991ed8_amd64 as a component of Red Hat Satellite 6.19
✅ Remediation
For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. Workaround: Deploying an RFC-compliant reverse proxy (such as nginx, Apache, HAProxy, or Caddy) in front of the ASGI server will reject malformed Host headers before they reach the application. This is the most straightforward mitigation that does not require code changes. If custom middleware is present, it should be updated to use `request.scope["path"]` instead of `request.url.path` for any security decisions. The ASGI scope path is derived from the HTTP request line and is not influenced by the Host header, so it reflects the actual request target.
