CVE-2026-4655 — Element Pack Addons for Elementor security vulnerability
The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the SVG Image Widget in versions up to and including 8.4.2. This is due to insufficient input sanitization and output escaping on SVG content fetched from remote URLs in the render_svg() function. The function fetches SVG content using wp_safe_remote_get() and then directly echoes it to the page without any sanitization, only applying a preg_replace() to add attributes to the SVG tag which does not remove malicious event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary JavaScript in SVG files that will execute whenever a user accesses a page containing the malicious widget.

Matched remediation archetype
Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
