On August 3, 2021, the Wordfence Threat Intelligence team initiated the disclosure process for two vulnerabilities we discovered in the Gutenberg Template Library & Redux Framework plugin, which is installed on over 1 million WordPress sites. One vulnerability allowed users with lower permissions, such as contributors, to install and activate arbitrary plugins and delete any post or page via the REST API. A second vulnerability allowed unauthenticated attackers to access potentially sensitive information about a site’s configuration.
