{"id":"CVE-2026-114052","summary":"vLLM 0.25.0 before 0.31.0 MOSS-Audio Memory Exhaustion via /tokenize mm_processor_kwargs","details":"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.","aliases":["GHSA-823j-m4cj-hmjf"],"modified":"2026-10-23T02:30:33.292828173Z","published":"2026-10-21T00:36:29.076Z","database_specific":{"cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114052.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114052.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-823j-m4cj-hmjf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114052"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vllm-0.25.0-before-0.31.0-moss-audio-memory-exhaustion-via-tokenize-mm-processor-kwargs"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vllm-project/vllm","events":[{"introduced":"e12b91b032daed2afc34d77cca20902cef957b3c"},{"fixed":"db9527a46873454610df6dbedf79a36d6bf1a7f6"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0.25.0"},{"fixed":"0.31.0"}]}]}}],"versions":["v0.31.0rc4","v0.31.0rc3","v0.31.0rc2","v0.31.0rc1","v0.30.1rc0","proto-v0.3.0","proto-v0.2.0","v0.29.1rc0","proto-v0.1.0","v0.28.1rc0","v0.27.2rc0","v0.26.1rc0","v0.25.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114052.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
