The Post Grid – Shortcode, Gutenberg Blocks and Elementor Addon for Post Grid < 7.9.6 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The The Post Grid – Shortcode, Gutenberg Blocks and Elementor Addon for Post Grid plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 7.9.5. This is 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.
