Page Builder: Pagelayer – Drag and Drop website builder <= 1.8.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Custom Attributes

The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom attributes in all versions up to, and including, 1.8.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
