Flowise · Flowise · CVE-2026-43995
**Name of the Vulnerable Software and Affected Versions**
Flowise versions prior to 3.1.0
**Description**
Multiple tool implementations bypass the centralized HTTP security wrapper (`httpSecurity.ts`), which is designed to provide Server-Side Request Forgery (SSRF) protections through deny-list validation, IP resolution validation, IP pinning, and loopback blocking. Instead of using this secured wrapper, certain tools directly import and invoke raw HTTP clients such as `node-fetch` and `axios`. This architectural failure allows outbound requests to be executed without validation, enabling access to internal network resources and the potential theft of cloud metadata and credentials. The affected components include `OpenAPIToolkit.ts`, `WebScraperTool.ts`, `MCP/core.ts`, and `Arxiv/core.ts`.
**Recommendations**
Update to version 3.1.0.
As a temporary workaround, restrict access to the `OpenAPIToolkit`, `WebScraperTool`, `MCP`, and `Arxiv` tools to minimize the risk of exploitation.
