Add custom input validation to sanitize user inputs before processing

Add WordPress sanitization functions like sanitize_text_field() or wp_kses() to theme files where user input is processed

Content Security Policy

all

Implement CSP headers to restrict script execution sources

Add to .htaccess: Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
Or use WordPress CSP plugin

🧯 If You Can't Patch

  • Switch to a different WordPress theme that is actively maintained and secure
  • Implement web application firewall (WAF) rules to block XSS payloads

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel > Appearance > Themes > MorningTime Lite version. If version is 1.3.2 or earlier, you are vulnerable.

Check Version:

In WordPress admin: Appearance > Themes, or check wp-content/themes/morningtime-lite/style.css for Version: line

Verify Fix Applied:

After updating, verify theme version is higher than 1.3.2. Test input fields that were vulnerable to ensure they now properly sanitize content.
