The Envira Gallery WordPress plugin before 1.16.2 does not verify that a user holds the capability WordPress reserves for installing Envira Gallery WordPress plugin before 1.16.2 code before processing its setup-wizard Envira Gallery WordPress plugin before 1.16.2-installation request, and does not restrict the installation to its own curated list, allowing a Multisite subsite Administrator to install an arbitrary WordPress.org-published Envira Gallery WordPress plugin before 1.16.2 into the network-shared Envira Gallery WordPress plugin before 1.16.2 directory, a privilege Multisite reserves for the network Super Admin.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
