The Woffice Core plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the wofficefilemanagerdelete() function in all versions up to, and including, 5.4.26. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The Woffice Core plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.4.21. This is due to missing or incorrect nonce validation on the 'wofficehandleuserapprovalactions' function. This makes it possible for unauthenticated attackers to approve registration for any user via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
