CVE-2024-3635 – The Post Grid < 7.5.0 - Editor+ Stored XSS via Grid Creation

https://notcve.org/view.php?id=CVE-2024-3635

The Post Grid WordPress plugin before 7.5.0 does not sanitise and escape some of its Grid settings, which could allow high privilege users such as Editor and above to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup). The The Post Grid – Shortcode, Gutenberg Blocks and Elementor Addon for Post Grid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 7.4.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. • https://wpscan.com/vulnerability/63cbe5f4-fe0f-499f-a964-cf4fbedcfa25 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
