Home page URL: Security reports for Mesmerize Companion
Application: Mesmerize Companion
Date: Feb 19, 2026
Research Description: The Mesmerize Companion plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on the "openPageInCustomizer" and "openPageInDefaultEditor" functions in all versions up to, and including, 1.6.158. This makes it possible for authenticated attackers - with subscriber level access and above, on websites with the Mesmerize theme activated - to mark arbitrary pages as maintainable, wrap their content in custom sections, change page template metadata, and toggle the default editor flag without proper authorization.
Affected versions: max 1.6.162.

Research Description: The Mesmerize Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'mesmerize_contact_form' shortcode in all versions up to, and including, 1.6.148 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
Affected versions: max 1.6.149.
Status: vulnerable
