Summary
The WP Shamsi plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the deactivate() function hooked via init() in versions up to, and including, 4.1.0. This makes it possible for unauthenticated attackers to deactivate arbitrary plugins on the site. This can be used to deactivate security plugins that aids in exploiting other vulnerabilities.
