On March 29, 2022, the Wordfence Threat Intelligence team initiated the disclosure process for a critical vulnerability in the Elementor plugin that allowed any authenticated user to upload arbitrary PHP code. Elementor is one of the most popular WordPress plugins and is installed on over 5 million websites.
We sent our disclosure to the official Elementor security contact email address on March 29, and followed up on April 5, 2022. As we did not receive a response by April 11, 2022, we sent the disclosure to the WordPress plugins team. A patched version of the plugin, 3.6.3, was released the next day on April 12, 2022.
Wordfence Premium, Wordfence Care, and Wordfence Response users received a firewall rule protecting against this issue on March 29, 2022. Sites still running the free version of Wordfence will receive the same protection 30 days later, on April 28, 2022.
