GHSA-2x8m-83vc-6wv4 · Severity: high · Ecosystem: npm — Flowise: SSRF Protection Bypass (TOCTOU & Default Insecure)
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.
Conclusion & alert: CVE-2026-41272 is rated Exploit Available (50/100): CVSS High severity, with low exploitation likelihood (EPSS 0.23%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
