The Page Builder: Pagelayer – Drag and Drop website builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Button Widget in all versions up to, and including, 1.8.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
The Page Builder: Pagelayer WordPress plugin before 1.8.0 doesn't prevent attackers with administrator privileges from inserting malicious JavaScript inside a post's header or footer code, even when unfiltered_html is disallowed, such as in multi-site WordPress configurations.

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. This appears to be a reintroduction of a vulnerability patched in version 1.7.7.
The Page Builder: Pagelayer WordPress plugin before 1.7.8 doesn't prevent attackers with author privileges and higher from inserting malicious JavaScript inside a post's header or footer code.
