OWASP Top 10 Mitigation Guide.

You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: Cybersecurity & Privacy
- Use case: OWASP Top 10 Mitigation Guide
- Source task:
  - Write a practical mitigation guide for the OWASP Top 10 vulnerabilities specific to a {{language_framework}} application. For each vulnerability:
  - 1. a plain-English explanation of the risk
  - 2. a vulnerable code example
  - 3. the secured version of the code
  - 4. automated detection method (SAST tool, linting rule)
  - 5. a test case to verify the mitigation is in place. Focus on {{vulnerability_area_injection_auth_data_exposure_etc}} if a specific area is the priority

# Goal
For each OWASP vulnerability: explanation, vulnerable example, fixed code, SAST detection, and a verification test.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
For each OWASP vulnerability: explanation, vulnerable example, fixed code, SAST detection, and a verification test.
