CVE-2026-79750: CWE-639: Authorization Bypass Through User-Controlled Key in samanhappy mcphubCVE-2026-79750 0 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 1.0.30, MCPHub scopes non-admin users to servers they own (list views and config edits enforce ownership), but the tool-execution API does not. Any authenticated non-admin user can invoke tools on MCP servers owned by other users — servers they cannot even see in GET /api/servers. Because connected MCP servers carry real capability (filesystem, HTTP fetch, cloud APIs with the owner's keys), this is cross-tenant compromise: demonstrated arbitrary host file read (/etc/passwd, another user's secrets) and SSRF. This issue has been patched in version 1.0.30. Join the discussion | CVE Database V5 | 08/31/2026, 17:54:14 UTC Added: 08/31/2026, 18:07:42 UTC |
