The Post Grid Gutenberg Blocks – PostX plugin for WordPress versions up to and including 5.1.0 is vulnerable to a stored cross-site scripting (XSS) flaw via the display_name user field. This vulnerability arises from insufficient input sanitization and output escaping, allowing an attacker with Subscriber-level privileges to inject malicious scripts that execute when other users view affected pages. The issue stems from WordPress core's pre_user_display_name filter encoding certain characters but leaving double-quotes unescaped, enabling script injection through attribute breakouts.

The Post Grid Gutenberg Blocks – PostX WordPress plugin is vulnerable to stored cross-site scripting (XSS) via the display_name user field in all versions up to and including 5.1.0. This vulnerability arises from insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts that execute when users access affected pages. The issue stems from WordPress core's pre_user_display_name filter encoding certain characters but leaving double-quotes intact, enabling a Subscriber-level user to inject malicious payloads that break out of HTML attributes.
