medium 6.4 CVE-2026-110017 · published 2026-10-16

Stored cross-site scripting (XSS) in Quick PayPal Payments (6.0.4 and older)

Affected: 6.0.4 and older
Fixed in: 6.0.5 *
Access needed (per CVSS): Needs a low-level account (e.g. subscriber)
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Quick PayPal Payments: Payment Button & Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form' parameter in all versions up to, and including, 6.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because wp_kses_post strips only HTML tags, a quote-breaking payload containing no angle brackets survives post save intact, and the injected script fires for every viewer of the post — including higher-privileged Editors and Administrators who routinely preview a Contributor's pending content.

Details from the advisory

The Quick Paypal Payments WordPress plugin through 5.7.50 does not verify the paid amount, receiver, or payment status in its PayPal IPN handler and marks an order paid on an order-token match alone, so a buyer who pays an arbitrary small amount can have a full-price order marked paid.
