Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
vLLM through 0.29.0 reads entire remote or inline media (audio, images and similar) into memory before checking its documented size and item limits, including the audio size cap and per-prompt item limits. A remote attacker who can reach the API server, batch runner or Rust frontend /tokenize route can send oversized or numerous media to exhaust memory and bandwidth, causing denial of service. The chat and batch endpoints require an API key when one is configured, while /tokenize does not. Upgrade to vLLM 0.30.0 or later.
