Mitigate without a patch
Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
