Vulnerability Overview

The WP STAGING Pro WordPress Backup Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.6.0. This is due to missing or incorrect nonce validation on the 'sub' parameter called from the WP STAGING WordPress Backup Plugin - Backup Duplicator & Migration plugin. This makes it possible for unauthenticated attackers to include any local files that end in '-settings.php' via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

WP STAGING Pro WordPress Backup Plugin <= 5.6.0 carries this weakness at sub, and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For WP STAGING Pro WordPress Backup Plugin the fix is 5.6.1: builds <= 5.6.0 are affected, anything from 5.6.1 onward is not.

Remediation

Update to version 5.6.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP STAGING Pro WordPress Backup Plugin: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP STAGING Pro WordPress Backup Plugin 5.6.1 closes this, and updating the plugin is the step that ends it.
