Doc Text:
A flaw was found in vllm. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by bypassing file size restrictions during multimodal chat audio processing. By submitting requests with oversized audio files, an attacker can force the server to allocate excessive memory and Central Processing Unit (CPU) resources during decoding.

Description OSIDB Bzimport 2026-09-26 13:32:55 UTC
vllm before 0.29.0 fails to enforce VLLM_MAX_AUDIO_CLIP_FILESIZE_MB limit in multimodal chat audio decoding, allowing unauthenticated clients to bypass file size restrictions. Attackers can submit oversized audio files through chat endpoints to consume excessive memory and CPU resources during decoding.
