Potential fix for https://github.com/byron-github-school/skills-copilot-codespaces-vscode/security/code-scanning/1

To fix the vulnerability, the application should avoid using untrusted DOM text as HTML without proper encoding. The single best solution in this case is to assign user input to textContent instead of innerHTML. textContent treats input as plain text instead of HTML, ensuring that any HTML meta-characters are not interpreted, and thereby blocking XSS attacks.

Where to change:
In member.js, change line 5 to use textContent instead of innerHTML.

What is needed:

  • No new methods or imports are required.
  • Only the assignment statement needs to be updated.
