Summary

The Envira Gallery WordPress plugin before 1.16.2 does not check that a user holds the WordPress capability required to install plugins before it processes its setup-wizard installation request (CWE-269). This lets a Multisite subsite Administrator install any plugin published on WordPress.org into the network-shared plugins directory, a privilege reserved for the network Super Admin. A public exploit is linked in the references.

Description from the CNA

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.
