# Suggested repair

1. **Encode output data:**
Encode all user-generated content before displaying it on a web page. This ensures that any potentially malicious scripts are treated as plain text rather than executable code. For example, convert special characters such as <, >, and & to their respective HTML entities (&lt;, &gt;, and &amp;).

2. **Input validation and filtering:**
Strictly validate and filter user input data to ensure it conforms to the expected format.

3. **Use Content Security Policy (CSP):**
Implement a Content Security Policy to restrict the sources from which scripts can be executed.

4. **Regular security audits:**
Regularly conduct code and system security audits to promptly identify and fix potential security vulnerabilities.
