{"id":"CVE-2026-79744","aliases":["GHSA-4gc8-885f-qj36"],"url":"https://o3.security/vulnerability/CVE-2026-79744","summary":"MCPHub: Missing Authorization on `PUT /api/system-config` Lets Any Non-Admin Rewrite Global Security Configuration","details":"MCPHub is a unified hub for centrally managing and dynamically orchestrating multiple MCP servers/APIs into separate endpoints with flexible routing strategies. Prior to version 1.0.29, MCPHub's PUT /api/system-config endpoint (handler updateSystemConfig) performs no authorization check. It is protected only by the app-wide authentication middleware and a rate limiter — it never inspects req.user.isAdmin. This issue has been patched in version 1.0.29.","published":"2026-08-31T17:56:38.995Z","modified":"2026-09-02T03:47:20.927956779Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/samanhappy/mcphub/releases/tag/v1.0.29"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79744.json"},{"type":"ADVISORY","url":"https://github.com/samanhappy/mcphub/security/advisories/GHSA-4gc8-885f-qj36"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79744"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-02T03:47:20.927956779Z"}}
