Vulnerability Overview

Authenticated Arbitrary File Creation via Export function vulnerability in GiveWP's GiveWP plugin <= 2.20.2 at WordPress.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity.

CWE-285: Improper Authorization

Reaching this weakness in GiveWP <= 2.20.2 takes any authenticated account. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For GiveWP the fix is 2.21.0: builds <= 2.20.2 are affected, anything from 2.21.0 onward is not.

Remediation

Update to version 2.21.0, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: GiveWP 2.21.0 closes this, and updating the plugin is the step that ends it.
