Implement strict CSP headers to prevent inline script execution and restrict script sources.

Add to .htaccess: Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
Add to nginx config: add_header Content-Security-Policy "default-src 'self'; script-src 'self'";

Plugin Deactivation

all

Temporarily disable the Twice Commerce plugin until patched.

wp plugin deactivate twice-commerce
Or via WordPress admin: Plugins > Installed Plugins > Twice Commerce > Deactivate

🧯 If You Can't Patch

  • Implement Web Application Firewall (WAF) rules to block XSS payloads
  • Disable the Twice Commerce plugin entirely and use alternative e-commerce solutions

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel: Plugins > Installed Plugins, look for Twice Commerce version. If version is 1.3.1 or earlier, you are vulnerable.

Check Version:

wp plugin list --name=twice-commerce --field=version

Verify Fix Applied:

After updating, verify Twice Commerce plugin shows version 1.3.2 or later in WordPress admin plugins list.

📡 Detection & Monitoring
