"report_markdown": "I can assist you in identifying potential security vulnerabilities in the provided code snippets. However, I need you to provide the specific code snippets that you believe are vulnerable. Please paste the relevant code from the provided files, and I'll guide you through the vulnerabilities and suggest corrected versions.\n\nSince you haven't provided any code yet, I'll give you an example of how I would approach this task. Let's say you provide the following code snippet from the `app.js` file:\n\n```javascript\n// 2. 🚨 THE SQL INJECTION VULNERABILITY 🚨\napp.get('/login', (req, res) => {\n const user = req.query.username || '';\n const query = \"SELECT * FROM users WHERE username = '\" + user + \"'\";\n \n db.get(query, (err, row) => {\n if (row) res.send(`Welcome ${row.username}!`);\n else res.status(401).send(\"Invalid\");\n });\n});\n```\n\n**Vulnerability:** SQL Injection\n\n**Description:** The code is vulnerable to SQL injection attacks. The `username` parameter is directly inserted into the SQL query without any sanitization or parameterization. This allows an attacker to inject malicious SQL code by manipulating the `username` query parameter.\n\n**Corrected Version:**\n\n```javascript\n// 2. 🚨 THE SQL INJECTION VULNERABILITY 🚨 (Corrected)\napp.get('/login', (req, res) => {\n const user = req.query.username || '';\n const query = \"SELECT * FROM users WHERE username = ?\";\n \n db.get(query, [user], (err, row) => {\n if (row) res.send(`Welcome ${row.username}!`);\n else res.status(401).send(\"Invalid\");\n });\n});\n```\n\nIn the corrected version, we use a parameterized query with a placeholder (`?`) for the `username` parameter. We then pass the `user` variable as an array to the `db.get()` method. This prevents SQL injection attacks.\n\nPlease provide the specific code snippets you'd like me to review, and I'll guide you through the vulnerabilities and suggest corrected versions."
