Vulnerability Overview

The WP Tools plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.18. This is due to missing or incorrect nonce validation on the deactivate_mu_plugin() function. This makes it possible for unauthenticated attackers to rename arbitrary files (which is the equivalent of arbitrary file deletion) via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 5.19, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
