CVE-2021-24524 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the GiveWP WordPress plugin, affecting versions < 2.12.0. It carries a CVSS score of 4.8 (reachable over the network; low attack complexity). Exploitation requires an authenticated account.

Vulnerability Overview

The GiveWP – Donation Plugin and Fundraising Platform WordPress plugin before 2.12.0 did not escape the Donation Level setting of its Donation Forms, allowing high privilege users to use Cross-Site Scripting payloads in them.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in GiveWP < 2.12.0 takes any authenticated account. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For GiveWP the fix is 2.12.0: builds < 2.12.0 are affected, anything from 2.12.0 onward is not.

Remediation

Update to version 2.12.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to GiveWP: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: GiveWP 2.12.0 closes this, and updating the plugin is the step that ends it.
