NVD Description

Note: Versions mentioned in the description apply only to the upstream vllm-cu129 package and not the vllm-cu129 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

vLLM versions before 0.28.0 fail to validate audio sample rate headers in the transcription endpoint, allowing authenticated clients to bypass duration checks. Attackers can submit forged FLAC headers with inflated sample rates to trigger excessive memory allocation and crash the API server process affecting all tenants.
