What is CVE-2026-85657?

The PublishPress Authors plugin for WordPress is susceptible to a Stored Cross-Site Scripting vulnerability through the 'profile_fields_user_email_value_prefix' parameter. This weakness arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Author-level access or higher to inject arbitrary scripts. When users interact with affected links, these scripts execute, potentially compromising user data and site integrity.
