vLLM (`MediaConnector` SSRF): SSRF via `load_from_url` in multimodal input handling

Impact

SSRF via load_from_url in multimodal input handling

Who can reach it

Unauthenticated request supplying an image URL — reaches cloud metadata endpoints and internal control planes

What to do

Upgrade and block link-local metadata (169.254.169.254) at the pod network layer. Provider-owned: IMDS reachability from tenant pods is an infrastructure decision
