CVE-2026-114052

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.
