| Package | Affected versions | Patched versions |
|---|---|---|
| vllm | ≥ 0.22.0, < 0.24.0 | 0.24.0 |
| vllm | ≥ 0.22.0, < 0.24.0 | 0.24.0 |
vLLM from 0.22.0 before 0.24.0 contains a denial of service vulnerability that allows remote attackers to terminate EngineCore by bypassing logprob_token_ids limits in the Rust gRPC frontend. Attackers can send Generate or GenerateStream requests with output_logprobs enabled and more than 128 output_candidates.token_ids, triggering a fatal sampler exception that crashes the engine.
