## What is CVE-2021-24570?

CVE-2021-24570 is a medium-severity cross-site scripting vulnerability in Unknown Accept Donations with PayPal, published on 1 Nov 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Accept Donations with PayPal WordPress plugin before 1.3.1 offers a function to create donation buttons, which internally are posts. The process to create a new button is lacking a CSRF check. An attacker could use this to make an authenticated admin create a new button. Furthermore, one of the Button field is not escaped before being output in an attribute when editing a Button, leading to a Stored Cross-Site Scripting issue as well.
