At a glance

CVE-2021-24572 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Accept Donations with PayPal & Stripe WordPress plugin, affecting versions < 1.3.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.3.1; sites on affected versions should update now. Disclosed October 2021, reported by dc11.

Vulnerability Overview

The Accept Donations with PayPal WordPress plugin before 1.3.1 provides a function to create donation buttons which are internally stored as posts. The deletion of a button is not CSRF protected and there is no control to check if the deleted post was a button post. As a result, an attacker could make logged in admins delete arbitrary posts

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 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)

Reaching this weakness in Accept Donations with PayPal & Stripe < 1.3.1 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 Accept Donations with PayPal & Stripe the fix is 1.3.1: builds < 1.3.1 are affected, anything from 1.3.1 onward is not.

Remediation

Update to version 1.3.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Accept Donations with PayPal & Stripe: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Accept Donations with PayPal & Stripe 1.3.1 closes this, and updating the plugin is the step that ends it.
