Flowise: SSRF Protection Bypass (TOCTOU & Default Insecure)
Summary
Flowise: SSRF Protection Bypass (TOCTOU & Default Insecure)
Original description
The description as published by the source.
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the core security wrappers (secureAxiosRequest and secureFetch) intended to prevent Server-Side Request Forgery (SSRF) contain multiple logic flaws. These flaws allow attackers to bypass the allow/deny lists via DNS Rebinding (Time-of-Check Time-of-Use) or by exploiting the default configuration which fails to enforce any deny list. This vulnerability is fixed in 3.1.0.
