CVE-2026-114052 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
