Automated scanners are already hunting for vulnerable Craft CMS sites. Attackers can run arbitrary PHP on your server, steal your database, install backdoors, compromise other sites on the same host, and use it as a staging point for further attacks.

Assess your exposure

Find all servers running Craft CMS. Check current versions. Look for suspicious log entries, unexpected file changes, and unusual network connections.

Patch now

Update to the latest Craft CMS version. Test in staging first if you can.

If patches aren't available yet:

  • Block known attack patterns with a WAF
  • Restrict access to the Craft admin interface
  • Use IP whitelisting for admin access
  • Disable non-essential functionality

Long-term

  • Apply least privilege to server accounts
  • Separate web servers from databases
  • Consider containerization
  • Update your incident response plan
