CVE-2024-13398: NAA986 Checkout For PayPal

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Checkout for PayPal plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'checkout_for_paypal' shortcode in all versions up to, and including, 1.0.32 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
