High Severity Vulnerability Patched in Access Demo Importer Plugin

The Wordfence Threat Intelligence team discovered a vulnerability in Access Demo Importer, a WordPress plugin installed on over 20,000 sites. This flaw made it possible for authenticated attackers with just subscriber level access to upload arbitrary files that could be used to achieve remote code execution. On sites with open registration, an anonymous user could easily register and exploit this vulnerability.

As the vendor was unresponsive, they escalated the issue to the WordPress.org plugins team. The plugins team responded immediately and closed the plugin for downloads on August 27, 2021, pending a full review. A partially patched version of the plugin was reopened for downloads around September 7, 2021. After following up with the developer and the WordPress plugins team, a fully patched version of the plugin was released on September 21, 2021.

Wordfence Premium users received a firewall rule to protect against any exploits targeting this vulnerability on August 9, 2021. Sites still using the free version of Wordfence received the same protection on September 8, 2021. As per the WordFence responsible disclosure policy, they are now fully disclosing the vulnerability details because enough time has elapsed since the fix was released.

If you have not already done so, we strongly recommend updating the latest version of the plugin available, 1.0.7, as soon as possible to ensure your site is not vulnerable to this security issue.
