The Co-Authors, Multiple Authors and Guest Authors in an Author Box with PublishPress Authors plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘profile_fields_user_email_value_prefix’ parameter in all versions up to, and including, 4.15.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user clicks on a link.
