CVE-2025-11859: Coenjacobs PayPal Donation Shortcode

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Paypal Donation Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'paypal' shortcode in all versions up to, and including, 0.1. This is due to the plugin not properly sanitizing user input and output of the 'title' and 'text' parameters. 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.
