Flowise allows arbitrary file write to RCE

Flowise

An attacker could write files with arbitrary content to the filesystem via the /api/v1/document-store/loader/process API. An attacker can reach RCE(Remote Code Execution) via file writing. All file writing functions in packages/components/src/storageUtils.ts are vulnerable.

Still cooking for npm (flowise) and Flowise.

## Flowise allows arbitrary file write to RCE
Severity: critical. Patch status: fix status unknown.
Affected: Flowise
Ids: CVE-2025-71338

An attacker could write files with arbitrary content to the filesystem via the /api/v1/document-store/loader/process API. An attacker can reach RCE(Remote Code Execution) via file writing. All file writing functions in packages/components/src/storageUtils.ts are vulnerable.

## Steps
1. This incident involves a provider (ai-gateways). Search config, CI and env templates (.env.example, wrangler.toml, vercel.json, terraform, workflow secrets) for credentials stored there. List each secret by name, where it is used, and how to rotate it. Never print secret values.
2. No fix yet on flowise <= 2.2.7. Flowise <= 2.2.7: the CVE record names no fix; check the vendor advisory before assuming there is none. Until one ships: restrict network access to it.

## Fix by release line
| Line | State | Fix | Until then |
|---|---|---|---|
| flowise <= 2.2.7 | no fix yet | — | restrict network access to it |
| Flowise <= 2.2.7 | not named in the CVE record | check the vendor advisory: https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-8vvx-qvq9-5948 | restrict network access to it |
