CVE-2022-3983 – Checkout for PayPal < 1.0.14 - Contributor+ Stored XSS

https://notcve.org/view.php?id=CVE-2022-3983

The Checkout for PayPal WordPress plugin before 1.0.14 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks El complemento de WordPress Checkout for PayPal anterior a 1.0.14 no valida ni escapa algunos de sus atributos de código corto antes de devolverlos a la página, lo que podría permitir a los usuarios con un rol tan bajo como el de colaborador realizar ataques de cross site scripting almacenado. The Checkout for PayPal plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes ('item_description' and 'amount') within the ‘checkout_for_paypal_button_handler’ function in versions up to, and including, 1.0.13 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.  • https://wpscan.com/vulnerability/0b48bbd6-7c77-44b8-a5d6-34e4a0747cf1 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
