  1. Affected< 3.5.5
  2. Patched in3.5.5

Update to 3.5.5 or newer.

You are affected if you run < 3.5.5. Version 3.5.5 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Count per Day.
  • 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 3.5.5, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch Count per Day to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Julien Rentrop.

The Count per Day plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
