This is due to a missing capability check and missing nonce validation on the pg_install_profilegrid() AJAX handler registered via wp_ajax_pg_install_profilegrid.

Executive Summary

The vulnerability exists in the Memberships and User Profiles for WooCommerce – ProfileGrid WooCommerce Integration plugin for WordPress, versions up to and including 3.4. It allows authenticated users with Subscriber-level access or higher to install and activate the ProfileGrid plugin without proper authorization.

This happens because the AJAX handler pg_install_profilegrid() lacks a capability check and nonce validation, which are security measures that should prevent unauthorized actions.

Impact Analysis

An attacker with at least Subscriber-level access can exploit this vulnerability to install and activate a plugin (ProfileGrid) without permission. This could lead to unauthorized changes to the WordPress environment.

While the vulnerability does not directly compromise confidentiality or availability, it can lead to integrity issues by allowing unauthorized plugin installation and activation, potentially enabling further malicious actions.

Mitigation Strategies

To mitigate this vulnerability, you should update the Memberships and User Profiles for WooCommerce – ProfileGrid WooCommerce Integration plugin to a version later than 3.4 where the issue is fixed.

Additionally, restrict Subscriber-level users from accessing plugin installation or activation features until the update is applied.

Consider monitoring and limiting AJAX requests to the wp_ajax_pg_install_profilegrid handler to prevent unauthorized plugin installation.
