- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

## Affected

- wpxpo WowRevenue – Product Bundles & Bulk Discounts: through 2.1.3

## Description

The WowRevenue plugin for WordPress is vulnerable to unauthorized plugin installation due to a missing capability check in the 'Notice::install_activate_plugin' function in all versions up to, and including, 2.1.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to install arbitrary plugins on the affected site's server which may make remote code execution possible.

## What to do

- Check your stack: if you ship or depend on wpxpo WowRevenue – Product Bundles & Bulk Discounts, no fixed version is listed yet; follow the vendor advisory per the references below.
