{"cve":"CVE-2026-57173","nvd":{"published":"2026-09-16T17:17:24.603","modified":"2026-10-07T14:24:22.100","status":"Analyzed","description":"vLLM is an inference and serving engine for large language models. Prior to 0.24.0, the input_audio handling path for /v1/chat/completions calls AudioMediaIO.load_bytes or AudioMediaIO.load_file without passing VLLM_MAX_AUDIO_DECODE_DURATION_S to the shared audio decoder. An unauthenticated client can therefore submit a small compressed audio input that expands into a very large float32 PCM allocation, bypassing the duration guard already used by /v1/audio/transcriptions and causing an out-of-memory worker crash. Inline data URLs reach this path without being bounded by VLLM_AUDIO_FETCH_TIMEOUT. The issue affects deployments serving an audio-capable model, and authentication changes only the deployment-specific reachability. This issue is fixed in version 0.24.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-770"],"references":["https://github.com/vllm-project/vllm/commit/3d20275bb4d434f53055c3c0b645fd8bb072965e","https://github.com/vllm-project/vllm/pull/45908","https://github.com/vllm-project/vllm/releases/tag/v0.24.0","https://github.com/vllm-project/vllm/security/advisories/GHSA-hcwq-8wjf-3gcr"],"products":["vllm:vllm"],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-57173","score":0.0073,"percentile":0.53991,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-hcwq-8wjf-3gcr","url":"https://osv.dev/vulnerability/GHSA-hcwq-8wjf-3gcr","summary":"vLLM: Unauthenticated audio decompression-bomb DoS in /v1/chat/completions","modified":"2026-10-01T17:56:17.490546142Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.24.0"],"fixed":["0.24.0"]}]},{"id":"PYSEC-2026-4179","url":"https://osv.dev/vulnerability/PYSEC-2026-4179","summary":"vLLM: Unauthenticated audio decompression-bomb DoS in /v1/chat/completions","modified":"2026-10-01T17:45:09.322181474Z","packages":[{"ecosystem":"PyPI","name":"vllm","purl":"pkg:pypi/vllm","ranges":["<0.24.0"],"fixed":["0.24.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
