2. Broken authentication

3. Carriage Return and Line Feed (CRLF) Injection

4. Cipher transformation insecure

5. Components with known vulnerabilities

6. Cross-Origin Resource Sharing (CORS) Policy

7. Credentials management

8. Cross-site request forgery (CSRF)

9. Cross-site scripting (XSS)

10. Directory indexing

11. Directory traversal
