CVE-2024-4107Public exploitNetwork attack vector

Stored script execution via unescaped page parameters

Published May 9, 2024 · Updated Apr 8, 2026

Stored cross-site scripting in Elementor Pro 3.21.0 and earlier allows remote authenticated users to inject scripts into WordPress pages. The page builder stores several attacker-controlled parameters without sufficient input sanitization and renders them without output escaping; public records do not name the parameters or code locus. Contributor-level access is required, and the script executes in another visitor's browser when an injected page is opened, enabling actions within that visitor's WordPress session.
