CVE-2026-5243Network attack vector

Stored XSS via unescaped navigation menu setting

Published May 14, 2026 · Updated May 14, 2026

Stored XSS in The Plus Addons for Elementor 6.4.11 and earlier allows remote authenticated users to inject scripts into pages. The Navigation Menu Lite widget renders the menu_hover_click parameter without sufficient input sanitization or output escaping, so saved markup is emitted as executable browser code. Contributor-level access or higher is required to store the payload, which executes whenever a user opens the affected page and permits actions in that user's browser context.
