Copilot Autofix
AI over 1 year ago
To fix the reflected cross-site scripting vulnerability, we need to sanitize the user-provided request.url before incorporating it into the msg string and writing it to the HTTP response. The best way to achieve this is by using a well-known library for escaping HTML, such as escape-html.
- General Fix: Use contextual output encoding/escaping before writing user input to the response.
- Detailed Fix: Import the
escape-htmllibrary and use it to sanitizerequest.urlbefore constructing themsgstring. - Specific Changes: Modify the
denyfunction to escape themsgparameter before writing it to the response. - Required Changes: Import the
escape-htmllibrary, update thedenyfunction, and sanitize themsgstring.
