CWE-79

The WP Event Manager WordPress plugin before 3.1.23 does not escape some of its Field Editor settings when outputting them, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

The Shop Page WP WordPress plugin before 1.2.8 does not sanitise and escape some of the Product fields, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

The BetterLinks WordPress plugin before 1.2.6 does not sanitise and escape some of imported link fields, which could lead to Stored Cross-Site Scripting issues when an admin import a malicious CSV.

The check_privacy_settings AJAX action of the WordPress GDPR WordPress plugin before 1.9.26, available to both unauthenticated and authenticated users, responds with JSON data without an “application/json” content-type. Since an HTML payload isn’t properly escaped, it may be interpreted by a web browser led to this endpoint. Javascript code may be executed on a victim’s browser. If the victim is an administrator with a valid session cookie, full control of the WordPress instance may be taken (AJAX calls and iframe manipulation are possible because the vulnerable endpoint is on the same domain as the admin panel – there is no same-origin restriction).

The Accept Donations with PayPal WordPress plugin before 1.3.2 does not escape the Amount Menu Name field of created Buttons, which could allow a high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
