CVE-2026-41271
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, a Server-Side Request Forgery (SSRF) vulnerability exists in FlowiseAI's POST/GET API Chain components that allows unauthenticated attackers to force the server to make arbitrary HTTP requests to internal and external systems. By injecting malicious prompt templates, attackers can bypass the intended API documentation constraints and redirect requests to sensitive internal services, potentially leading to internal network reconnaissance and data exfiltration. This vulnerability is fixed in 3.1.0.

Flowise versions prior to 3.1.0 are vulnerable to an unauthenticated Server-Side Request Forgery (SSRF) in its API Chain components. If you are self-hosting Flowise to build LLM apps, an attacker could force your server to make requests to internal services or cloud infrastructure endpoints, potentially leading to data exfiltration.
