The WordPress Shortcodes Plugin — Shortcodes Ultimate WordPress plugin before 5.12.8 does not validate the user meta to be retrieved via the user shortcode, allowing any authenticated users such as subscriber to retrieve arbitrary user meta (except the user_pass), such as the user email and activation key by default.
Cross-Site Request Forgery (CSRF) vulnerability leading to Stored Cross-Site Scripting (XSS) in Vladimir Anokhin's Shortcodes Ultimate plugin <= 5.12.0 on WordPress.
The Shortcodes Ultimate WordPress plugin before 5.10.2 allows users with Contributor roles to perform stored XSS via shortcode attributes. Note: the plugin is inconsistent in its handling of shortcode attributes; some do escape, most don't, and there are even some attributes that are insecure by design (like [su_button]'s onclick attribute).
