The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to unauthorized post publication due to insufficient validation on the pagelayersavecontent() function in all versions up to, and including, 1.9.8.

The Page Builder: Pagelayer WordPress plugin before 1.8.1 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup)
