CVE-2026-43995: Flowise: SSRF Protection Bypass via Direct node-fetch / axios Usage (Patch Enforcement Failure)

Flowise introduced SSRF protections through a centralized HTTP security wrapper (httpSecurity.ts) that implements deny-list validation and IP pinning logic.

However, multiple tool implementations directly import and invoke raw HTTP clients (node-fetch, axiosInstead of using the secured wrapper.

Because enforcement is neither mandatory nor centralized, these tools bypass SSRF mitigation entirely, restoring full SSRF capability even after the patch.

This issue is distinct from specification trust issues and represents incomplete mitigation of previously addressed SSRF vulnerabilities.
