# CVE-2025-3248 Langflow RCE Scanner
## 🔍 Description
A powerful, unauthenticated RCE scanner for CVE-2025-3248 in vulnerable Langflow instances.
- **CVE**: 2025-3248
- **Type**: Remote Code Execution (Unauthenticated)
- **Affected**: Langflow < 1.3.0
- **Author**: Issam Junior ([@issamiso](https://t.me/issamiso))

## 💥 Vulnerability Overview
Langflow's `/api/v1/validate/code` endpoint insecurely executes user-supplied code using Python `exec()`, without authentication or sandboxing. This enables remote attackers to execute arbitrary Python code.
---
## ✅ Protection
- Upgrade to Langflow **1.3.0 or newer**
- Block access to `/api/v1/validate/code`
- Use proper code sandboxing (e.g., Pyodide, Docker, restricted ASTs)
