{"id":"CVE-2026-112268","summary":"sglang-router through 0.3.2 Authorization Bypass via Mesh HA Management Routes","details":"sglang-router (sgl-model-gateway) through 0.3.2 contains an authorization bypass vulnerability that allows holders of the data-plane API key to access mesh HA management routes because /ha/* endpoints skip control-plane Admin role checks. Attackers can read cluster topology, write gossiped configuration, change global rate limits, and call POST /ha/shutdown to silently dissolve HA coordination.","modified":"2026-10-21T02:55:50.956812974Z","published":"2026-10-19T13:55:17.198Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112268.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112268.json"},{"type":"PACKAGE","url":"https://github.com/sgl-project/sglang"},{"type":"ARTICLE","url":"https://github.com/sgl-project/sglang/blob/v0.5.22/sgl-model-gateway/src/server.rs#L641-L675"},{"type":"REPORT","url":"https://github.com/sgl-project/sglang/issues/45006"},{"type":"FIX","url":"https://github.com/sgl-project/sglang/pull/45017"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112268"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sglang-router-through-0.3.2-authorization-bypass-via-mesh-ha-management-routes"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sgl-project/sglang","events":[{"introduced":"0"},{"last_affected":"37c5899fc2100de1c9afd51a7b1977b2f8185a28"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"0.3.2"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["v0.3.2","v0.3.1.post3","v0.3.1.post2","v0.3.1.post1","v0.3.0","v0.2.15","v0.2.14.post2","v0.2.14.post1","v0.2.14","v0.2.13","v0.2.12","v0.2.11","v0.2.10","v0.2.9.post1","v0.2.9","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.0","v0.1.24","v0.1.23","v0.1.22","v0.1.21","v0.1.20","v0.1.19","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112268.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
