CVE-2026-44284 FastGPT: Stored MCP tool URL SSRF in FastGPT workflow execution

FastGPT is an AI Agent building platform. Prior to version 4.14.17, FastGPT had an inconsistent SSRF protection gap in MCP tool URL handling. The direct MCP preview/run endpoints already rejected internal/private network URLs, but the MCP tool create/update endpoints could still save an internal...

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 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...

CVE-2026-40351 FastGPT: NoSQL Injection in loginByPassword leads to Authentication Bypass

FastGPT is an AI Agent building platform. In versions prior to 4.14.9.5, the password-based login endpoint uses TypeScript type assertion without runtime validation, allowing an unauthenticated attacker to pass a MongoDB query operator object e.g., "$ne": "" as the password field. This NoSQL...
