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.","published":"2026-10-12T14:17:11.747","modified":"2026-10-12T14:17:11.870","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/sgl-project/sglang"},{"type":"WEB","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/audio_from_video.py#L128"},{"type":"WEB","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/base_processor.py#L996"},{"type":"WEB","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1783"},{"type":"WEB","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1801-L1803"},{"type":"WEB","url":"https://github.com/sgl-project/sglang/issues/43708"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/sglang-through-0.5.21-audio-decompression-amplification-via-load-audio"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-12T14:17:11.870"}}
