Create a `Config` class that stores and exposes the OpenAI API key, admin credentials, and system prompt through a public endpoint, implementing LLM06 at the infrastructure level. + +3. **Implement the vulnerable OpenAI client** wrapping the SDK with deliberate flaws: pass user input directly without sanitisation (LLM01), return full metadata including system prompt (LLM06/LLM10), expose `generate_long_response` with `max_tokens=4000` and no rate limiting (LLM04), and track `request_count` for usage pattern disclosure (LLM10). + +4. **Build the injectable SQLite database helper** with three SQL injection classes: string-interpolated `search_users` enabling `' OR 1=1--` attacks, `update_user` accepting arbitrary field/value parameters, and `execute_raw_sql` running any SQL statement. Seed with fake users and a secrets table containing plaintext credentials. + +5. **Create the dangerous plugin system** with `command_executor.py` using `subprocess.run(shell=True)` with no whitelist (LLM07/LLM08), and `file_reader.py` reading any path without validation. Add a `load_external_plugin` endpoint accepting a `plugin_url` to demonstrate LLM05. + +6. **Implement Flask route handlers** mapping each OWASP category to exploitable endpoints: `/api/chat` (LLM01/02/04/06), `/api/config` (LLM06 full dump), `/api/prompt-injection` (LLM01), `/api/dos/long-response` (LLM04), `/api/plugin/execute` (LLM07/08), `/api/admin/delete-user/` unauthenticated (LLM08), `/api/system/info` dumping `os.environ` (LLM06). + +7. **Build the web interface** as a single HTML page using Bootstrap. Render LLM responses with `innerHTML` so XSS payloads execute in the browser (LLM02). Add a vulnerability panel with all exploitable endpoints and a config viewer calling `/api/config`. + +8. **Document every vulnerability** in the `learn/` directory: `owasp-llm-overview.md` explaining each risk, `attack-walkthrough.md` with curl commands, and `mitigations.md` with concrete fixes. + +9. **Containerise** with Docker using `uv` for dependency management, binding only to `127.0.0.1:5000`, with `HEALTHCHECK` on `/health` and `data/` mounted as a volume. + +10. **Validate** by running every payload in `tests/attack_payloads.json`, confirming all ten OWASP LLM categories are reproducible, and verifying Docker isolation. + +## Key Concepts to Learn +- OWASP Top 10 for Large Language Model Applications +- Prompt injection — direct, indirect, and role manipulation +- LLM output handling and XSS/SQLi/RCE attack vectors +- Rate limiting, token budgets, and denial-of-service mitigation +- Plugin architecture security and principle of least privilege +- Secrets management and environment variable hygiene +- Supply chain risks in AI/ML applications +- Model metadata disclosure and model theft vectors + +## Deliverables +- Flask backend with all ten OWASP LLM vulnerabilities as live endpoints +- Vulnerable OpenAI client, SQLite helper, and plugin system +- Docker Compose environment with `uv` and volume isolation +- `learn/` directory with OWASP overview, attack walkthrough, and mitigations +- `tests/attack_payloads.json` with documented payloads for all ten categories +- Complete README with architecture diagram, API reference, and safety warnings + +--- +[![Cybersecurity Projects](https://img.shields.io/badge/Cybersecurity--Projects-Advanced-red?style=flat&logo=github)](https://github.com/CarterPerez-dev/Cybersecurity-Projects/tree/main/PROJECTS/advanced/prompt-scan) +[![Python](https://img.shields.io/badge/Python-3.11+-3776AB?style=flat&logo=python&logoColor=white)](https://www.python.org) +[![Flask](https://img.shields.io/badge/Flask-3.x-000000?style=flat&logo=flask&logoColor=white)](https://flask.palletsprojects.com) +[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) +[![OWASP LLM](https://img.shields.io/badge/OWASP-Top%2010%20LLM-orange?style=flat)](https://owasp.org/www-project-top-10-for-large-language-model-applications/)
