Title
Echo Knowledge Base <= 17.214.0 - Reflected Cross-Site Scripting via 'new_kb_config' Parameter
Summary
The Echo Knowledge Base – Documentation, FAQs, Chat & Smart Search plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'new_kb_config' parameter (specifically the article-mobile-break-point-v2 key, among other config keys interpolated into the <style> element) in versions up to, and including, 17.214.0 This is due to insufficient input sanitization and output escaping in EPKB_Frontend_Editor::fe_preview_config() and EPKB_Articles_Setup: on every knowledge base article page view, when the request supplies epkb_fe_reload_mode=on, an attacker-controlled JSON blob is merged over the stored KB configuration and several values are concatenated directly into a stylesheet emitted inside a literal <style> element without escaping (minify_css() does not strip <, > or /). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user (with Editor-level access or above, holding the manage_categories capability, or an Administrator) into performing an action such as clicking on a specially crafted link.

Title
Creative Addons for Elementor <= 1.5.12 - Authenticated (Contributor+) Stored Cross-Site Scripting
Summary
The Creative Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's widgets in all versions up to, and including, 1.5.12 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

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."
