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.","categories":["Unclassified"],"product":"sglang","vendor":"sgl-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109228","source_modified_at":"2026-10-14T17:52:09.025Z","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":0.00493,"percentile":0.4147,"score_date":"2026-10-23"},"published_at":"2026-10-12T14:04:32.029Z","modified_at":"2026-10-14T17:52:09.025Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109228","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T17:52:09.025Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109228","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/43705","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/entrypoints/openai/protocol.py#L592-L594","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/parser/conversation.py#L691","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/glm4v.py#L160-L167","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/sgl-project/sglang/blob/v0.5.21/python/sglang/srt/multimodal/processors/glm4v.py#L400","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-resource-budget-bypass-via-glm-v-video-parameters","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-14T17:51:42.680233Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T17:52:09.025Z","content_hash":"5ba6990973eb34e1b9b63fcf4014d3dea985a5884489048ffa3dfae478037627"}}
