Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

vLLM versions from 0.5.5 before 0.11.1 are vulnerable to a denial of service. An attacker who can send requests to the server can pass multimodal embedding inputs with the correct number of dimensions but a wrong shape, such as an incorrect hidden dimension, crashing the engine. Upgrade to vLLM 0.11.1 or later. As a workaround, restrict access to trusted users with an API key, or set --limit-mm-per-prompt to 0 for non-text modalities, though this leaves the model accepting only text.
