Vulnerabilities Patched in WP Page Builder

On February 15, 2021, the Wordfence Threat Intelligence team began the responsible disclosure process for several vulnerabilities in WP Page Builder, a plugin installed on over 10,000 sites. These vulnerabilities allowed any logged-in user, including subscribers, to access the page builder’s editor and make changes to existing posts on the site by default.

Wordfence Premium users received a firewall rule protecting against these vulnerabilities on February 15, 2021. Sites still running the free version of Wordfence received the same protection 30 days later, on March 17, 2021.
