Flowise: SSRF Protection Bypass via Direct node-fetch / axios Usage (Patch Enforcement Failure)

Assigner: GitHub_M
Reserved: 04.05.2026 Published: 11.05.2026 Updated: 11.05.2026

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, multiple tool implementations directly import and invoke raw HTTP clients (node-fetch, axios) instead of using the secured wrapper. These tools include (1) OpenAPIToolkit/OpenAPIToolkit.ts, (2) WebScraperTool/WebScraperTool.ts, (3) MCP/core.ts, and (4) Arxiv/core.ts. This vulnerability is fixed in 3.1.0.
