Widget Options – The #1 WordPress Widget & Block Control Plugin <= 4.1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting

The Widget Options – The #1 WordPress Widget & Block Control Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple functions in all versions up to, and including, 4.1.2 due to insufficient input sanitization and output escaping. 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.
