CVE-2026-44284

FastGPT (before 4.14.17) had an SSRF flaw in MCP tool URL handling. An authenticated user with permission to create/manage MCP toolsets could store an internal endpoint (e.g., http://localhost:3000/mcp) via the MCP tool create/update endpoints. The stored URL could be used later by the backend wo...

CVE-2026-42345 FastGPT: Cloud metadata endpoint SSRF protection bypass via port specification, IPv6 mapping, hex/decimal IP encoding, and trailing dot

FastGPT is an AI Agent building platform. In versions 4.14.11 and prior, FastGPT's isInternalAddress function in packages/service/common/system/utils.ts blocks cloud metadata endpoints using a fullUrl.startsWith check against a hardcoded list. This check can be bypassed using at least 7 different...

CVE-2026-42344 FastGPT: DNS rebinding TOCTOU bypass in isInternalAddress allows SSRF on all protected endpoints

FastGPT is an AI Agent building platform. In versions 4.14.11 and prior, FastGPT's isInternalAddress function in packages/service/common/system/utils.ts is vulnerable to DNS rebinding TOCTOU — Time-of-Check to Time-of-Use. The function resolves the hostname via dns.resolve4/dns.resolve6 and check...

CVE-2026-42344

FastGPT before 4.14.11 is vulnerable in isInternalAddress() (packages/service/common/system/utils.ts) to DNS rebinding TOCTOU, where DNS resolution for private-range checks occurs separately from the subsequent HTTP request. An attacker could exploit the window between validation and fetch to byp...
