Attackers can read cluster topology, write gossiped configuration, change global rate limits, and call POST /ha/shutdown to silently dissolve HA coordination.","state":0,"publishedAt":"2026-10-19T13:55:17.198+00:00","modifiedAt":"2026-10-22T02:48:54.213+00:00","affected":[{"ecosystem":"Vendor product","name":"sglang-router","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sgl-project\",\n                    \"product\": \"sglang-router\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"0.3.2\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:pypi/sglang-router\",\n                    \"repo\": \"https://github.com/sgl-project/sglang\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/sgl-project/sglang/issues/45006","https://github.com/sgl-project/sglang/pull/45017","https://github.com/sgl-project/sglang/blob/v0.5.22/sgl-model-gateway/src/server.rs#L641-L675","https://www.vulncheck.com/advisories/sglang-router-through-0.3.2-authorization-bypass-via-mesh-ha-management-routes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112268","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112268","identifiers":["CVE-2026-112268"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
