CSRF and Stored XSS Vulnerabilities in Accept Donations with PayPal WordPress Plugin

CVE-2021-24570 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N

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.
