{"id":"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.","aliases":["GHSA-4gc8-885f-qj36"],"modified":"2026-09-02T03:47:20.927956779Z","published":"2026-08-31T17:56:38.995Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79744.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/samanhappy/mcphub","events":[{"introduced":"0"},{"fixed":"9fb73ddf038122fed5ba095da35a01e3baecb011"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.29"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.0.28","v1.0.27","v1.0.26","v1.0.25","v1.0.24","v1.0.23","v1.0.22","v1.0.21","v1.0.20","v1.0.19","v1.0.18","v1.0.17","v1.0.16","v1.0.15","v1.0.14","v1.0.13","v1.0.12","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.12.17","v0.12.16","v0.12.15","v0.12.14","v0.12.13","v0.12.12","v0.12.11","v0.12.10","v0.12.9","v0.12.8","v0.12.7","v0.12.6","v0.12.5","v0.12.4","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.11.13","v0.11.12","v0.11.11","v0.11.10","v0.11.9","v0.11.8","v0.11.7","v0.11.6","v0.11.5","v0.11.4","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.6","v0.10.5","v0.10.4","v0.10.3","v0.10.2","v0.10.1","v0.10.0","v0.9.16","v0.9.15","v0.9.14","v0.9.13","v0.9.12","v0.9.11","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-79744.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
