CVE-2022-4623Public exploitNetwork attack vector

Stored XSS via unescaped shortcode attributes

Published Jul 4, 2023 · Updated Nov 22, 2024

Stored cross-site scripting in Nicdark ND Shortcodes before 7.0 allows remote authenticated users to inject script through shortcode attributes. The shortcode renderers place attacker-controlled class and color attribute values into page markup without validation or output escaping. Contributor-level access and WPBakery Page Builder initialization are required; viewing the crafted page executes the stored script in another user's browser.
