On August 25, 2021, the Wordfence Threat Intelligence team initiated the disclosure process for a vulnerability in Hashthemes Demo Importer, a WordPress plugin with over 7,000 installations.

This vulnerability allowed any authenticated user to completely reset a site, permanently deleting nearly all database content as well as all uploaded media.

As we did not receive a response from the developer for nearly a month, we contacted the WordPress plugins team with our disclosure on September 20, 2021. The plugin was temporarily removed from the repository the same day, and a patched version, 1.1.2, was made available on September 24, 2021, though it was not mentioned in the developer changelog.

Wordfence Premium customers received a firewall rule protecting against this vulnerability on August 25, 2021. Sites running the free version of Wordfence received the same rule 30 days later, on September 24, 2021.
