Smart Forms – when you need more than just a contact form smart-forms

  1. Affected< 2.6.26
  2. Patched in2.6.26

Update to 2.6.26 or newer.

You are affected if you run < 2.6.26. Version 2.6.26 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Smart Forms – when you need more than just a contact form.
  • No admin access? Run a passive check of your site. It reads public files only.
  • No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

  1. Update to version 2.6.26, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch Smart Forms – when you need more than just a contact form to get an email when the next vulnerability is published.
