# CVE-2026-9999 – Serverless Event Injection to Code Overwrite

![Severity: Critical](https://img.shields.io/badge/severity-critical-red)

## 📖 Overview

A path traversal vulnerability in a serverless platform’s event processing allows an attacker to overwrite the function’s source code, leading to remote code execution on subsequent invocations.

## ⚙️ Vulnerability Details

- **Type:** Path Traversal / Insecure File Write
- **Impact:** Remote Code Execution (RCE)
- **Root Cause:** The platform trusts the `object.key` field from storage events without sanitization, allowing `../` sequences to write to arbitrary paths within the function sandbox.

## 🧪 Exploit Demonstration

1. Start the vulnerable runtime:
   ```bash
   python vulnerable_serverless.py

Run the exploit:

bash
python exploit_event_injection.py
