Advisory

Source description from Wordfence Intelligence.

The 10Web Booster plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the two_deactivate_plugin function in versions up to, and including, 2.8.34. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to deactivate incompatible plugins.
