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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-409"],"vendors":[],"products":[],"references":[{"url":"https://github.com/sgl-project/sglang","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/audio_from_video.py#L128","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/base_processor.py#L996","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1783","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1801-L1803","tags":[]},{"url":"https://github.com/sgl-project/sglang/issues/43708","tags":[]},{"url":"https://www.vulncheck.com/advisories/sglang-through-0.5.21-audio-decompression-amplification-via-load-audio","tags":[]},{"url":"https://github.com/sgl-project/sglang/issues/43708","tags":[]}],"exploitRefs":[{"url":"https://github.com/sgl-project/sglang","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/audio_from_video.py#L128","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/base_processor.py#L996","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1783","tags":[]},{"url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/utils/common.py#L1801-L1803","tags":[]},{"url":"https://github.com/sgl-project/sglang/issues/43708","tags":[]},{"url":"https://github.com/sgl-project/sglang/issues/43708","tags":[]}],"hasPoc":true,"ai":null}
