Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Correos Oficial.
• 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. No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Correos Oficial to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Andrea Iodice.

The Correos Oficial plugin for WordPress is vulnerable to the unauthorized download of files in versions up to, and including, 1.3.0.0. This is due to insufficient validation on the supplied file path of a document being downloads. This makes it possible for unauthenticated attackers to download arbitrary files, such as sensitive configuration files like wp-config.php.
