{"id":"CVE-2026-109228","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-109228","summary":"SGLang through 0.5.21 Resource Budget Bypass via GLM-V Video Parameters","details":"SGLang through 0.5.21 contains a resource budget bypass vulnerability that allows remote attackers to override GLM-V video processing limits by supplying fps, max_frames, max_tokens_per_frame and max_image_tokens in the video_url object. Attackers can set these values arbitrarily high so glm4v.py decodes every frame of high-resolution video at full size, exhausting worker memory and denying service.","published":"2026-10-12T14:04:32.029Z","modified":"2026-10-13T02:46:50.855132621Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109228.json"},{"type":"PACKAGE","url":"https://github.com/sgl-project/sglang"},{"type":"ARTICLE","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/entrypoints/openai/protocol.py#L592-L594"},{"type":"ARTICLE","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/glm4v.py#L160-L167"},{"type":"ARTICLE","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/glm4v.py#L400"},{"type":"ARTICLE","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/parser/conversation.py#L691"},{"type":"REPORT","url":"https://github.com/sgl-project/sglang/issues/43705"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109228"},{"type":"PACKAGE","url":"https://pypi.org/project/sglang"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sglang-through-0.5.21-resource-budget-bypass-via-glm-v-video-parameters"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-13T02:46:50.855132621Z"}}
