Summary

vLLM from 0.25.0 before 0.31.0 contains a memory exhaustion flaw in MOSS-Audio model serving (CWE-770). The processor cache is an unbounded dictionary that stores a new processor for each distinct request-controlled mm_processor_kwargs value. An unauthenticated remote attacker can exhaust host memory and crash the API process through the /tokenize endpoint, which bypasses --api-key.

Description from the CNA

vLLM after 0.24.0 and before 0.31.0 contains a memory exhaustion vulnerability in MOSS-Audio model serving that caches a processor for every distinct request-controlled mm_processor_kwargs value in an unbounded dictionary. Unauthenticated attackers can send distinct or oversized mel_config values to the /tokenize endpoint, which bypasses --api-key, to exhaust host memory and crash the API process.
