CVE CVE-2022-3883
CVSS 6.5 (Medium)
Publicly Published November 18, 2022
Last Updated December 5, 2022
Researcher István Márton - Wordfence


The StopBadBots plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the stopbadbots_install_plugin() function in versions up to, and including, 3.04. This makes it possible for authenticated attackers with minimal permission, such as a subscriber, to install arbitrary plugins on the vulnerable site. This could be used to install additional vulnerable plugins that could aid in further compromise of the site.
