{"schema":"threatline.record/2","record":{"id":"CVE-2026-109226","aliases":[],"summary":"SGLang through 0.5.21 Audio Decompression Amplification via load_audio","details":"SGLang through 0.5.21 contains a decompression amplification vulnerability in load_audio that allows remote attackers to exhaust memory by submitting highly compressed audio decoded without duration or sample limits. Attackers can supply small FLAC-encoded silence files through audio_url or audio_data inputs that expand into massive PCM buffers, exhausting worker memory and CPU for denial of service.","categories":["Unclassified"],"product":"sglang","vendor":"sgl-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109226","source_modified_at":"2026-10-13T18:24:26.414Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"sglang","vendor":"sgl-project","versions":[{"version":"0","status":"affected","versionType":"semver","lessThanOrEqual":"0.5.21"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00464,"percentile":0.39228,"score_date":"2026-10-23"},"published_at":"2026-10-12T14:04:30.674Z","modified_at":"2026-10-13T18:24:26.414Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109226","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-13T18:24:26.414Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109226","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/sgl-project/sglang/issues/43708","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1783","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1801-L1803","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/audio_from_video.py#L128","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/base_processor.py#L996","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/sglang-through-0.5.21-audio-decompression-amplification-via-load-audio","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-13T18:23:46.746453Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-13T18:24:26.414Z","content_hash":"b78e1f6f1061b5700a108d22f658800a944ef215de2ff7f3c720a4010ba412dc"}}
