Missing Authorization
CVE CVE-2022-3883
CVSS 6.5 (Medium)
Publicly Published November 18, 2022
Last Updated October 23, 2024
Researcher István Márton - Wordfence

Description

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, 7.23. 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.
