HivePress <= 1.7.31 - Unauthenticated Stored Cross-Site Scripting via Custom User Attribute Value via Registration Form

The HivePress – Business Directory, Listings & Classified Ads Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '<custom user attribute field name, e.g. profile_test>' parameter in all versions up to, and including, 1.7.31 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have configured a text-type custom user attribute whose display format places %value% inside an HTML attribute context (e.g., the documented pattern &lt;a href="%value%"&gt;Custom link&lt;/a&gt;), and for front-end user profiles to be enabled — both of which reflect the plugin's standard, documented configuration.
