Summary

vLLM from 0.7.3 before 0.31.0 contains an uncontrolled resource consumption vulnerability that allows remote clients to control multimodal processor parameters by supplying per-request mm_processor_kwargs. Attackers can set large image size, patch count, crop count, or frame count values in Isaac, InternVL, H2OVL, and other processors to exhaust memory and terminate the shared server.

Remediation

1. Inventory every Vllm Vllm deployment, including staging.
2. Upgrade Vllm Vllm to 0.31.0.
3. Confirm the running version after the upgrade.
