Description
The Post Grid Master – Custom Post Types, Taxonomies & Ajax Filter Everything with Infinite Scroll, Load More, Pagination & Shortcode Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 3.4.11 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
