CVE-2026-4655Network attack vector

Stored XSS via unsanitized remote SVG output

Published Apr 8, 2026 · Updated Apr 8, 2026

Stored XSS in BdThemes Element Pack Addons for Elementor 8.4.2 and earlier allows remote authenticated users to inject JavaScript. The SVG Image Widget's render_svg() function fetches remote SVG content, adds tag attributes with preg_replace(), and echoes it without sanitization or output escaping. Contributor-level access is required to save the malicious widget, and the payload executes in a user's browser when the containing page is viewed.
