CVE-2026-116173 vLLM 0.22.0 before 0.24.0 Denial of Service via gRPC output_candidates.token_ids

vLLM from 0.22.0 before 0.24.0 contains a denial of service vulnerability that allows remote attackers to terminate EngineCore by bypassing logprobtokenids limits in the Rust gRPC frontend. Attackers can send Generate or GenerateStream requests with outputlogprobs enabled and more than 128...

PYSEC-2026-4325

vLLM is an inference and serving engine for large language models. Prior to 0.30.0, the Rust frontend's trackhttpmetrics middleware records the raw HTTP method token as a Prometheus label for requests reaching registered routes. An unauthenticated attacker can send unique arbitrary method tokens ...

An unauthenticated attacker can send unique arbitrary method tokens ...

CVE-2026-105759

The vLLM inference and serving engine for large language models is vulnerable to a Denial of Service (DoS) attack in versions prior to 0.30.0 . The root cause lies in the Rust frontend's track_http_metrics middleware, which records raw HTTP method tokens as Prometheus labels without validation or...

CVE-2026-105757

vLLM is an inference and serving engine for large language models. Prior to 0.30.0, structured-output request failures can escape request-scoped validation and reach the EngineCore fatal-error path. A per-request backend mismatch can re-raise a grammar compilation exception, padding produced by t...

CVE-2026-100650 vLLM before 0.29.0 Resource Exhaustion via Unbounded Media Materialization

vLLM through 0.29.0 fetches and fully materializes remote or inline media before enforcing its documented media controls the VLLMMAXAUDIOCLIPFILESIZEMB compressed-audio size cap, default 25 MB, and the per-modality --limit-mm-per-prompt item limits. Across four ingress paths — the shared...
