Editor PHP Object Injection in Page Builder by SiteOrigin <= 2.36.0 versions.

The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via panelsdata Parameter in all versions up to, and including, 2.34.3 due to insufficient input sanitization and output escaping.
