Ensure the fix aligns with the existing code patterns and framework. +4. **Implement the fix**: Modify the code cleanly, adding necessary security controls. +5. **Review**: Check that the fix does not break existing functionality or introduce new security holes. Add comments explaining the fix if appropriate. + +Consider edge cases: handle different input types, encoding contexts, and error conditions. Do not assume safe input; always validate and sanitize data at the earliest possible point. When in doubt, prefer stricter controls. + +Always provide a clear explanation of the change and its security impact.
