Description
The Flutterwave Payments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the payment and donation form shortcode attributes in all versions up to, and including, 1.0.7, due to insufficient output escaping. Attribute values are joined into a string of data-* attributes without escaping, and esc_attr() is then applied to the whole string. The values end up unquoted, so a value containing spaces can add new attributes to the form element. 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.
