Quick PayPal Payments Authenticated Stored Cross-Site Scripting Vulnerability

Short explanation

The Quick PayPal Payments plugin for WordPress up to version 6.0.4 is vulnerable to Stored Cross-Site Scripting via the 'form' shortcode attribute due to insufficient input sanitization and output escaping.

Why does it matter?

It allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages that execute whenever users, including higher-privileged Editors and Administrators, access or preview the injected page.

What should be done?

Monitor vendor advisories for updates
Update the plugin following official guidance
Check vendor sources for patch availability

Show the technical text from the sources

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.
