MEDIUM CVE-2026-15787 Deferred

Ultimate Addons navigation icons allow contributor stored XSS

Ultimate Addons for Elementor 2.9.1 and earlier does not safely handle the Navigation Menu widget's data-toggle-icon and data-close-icon attributes. A contributor can store an HTML-entity-encoded payload that survives WordPress sanitization, is decoded by the browser, and is inserted as markup by jQuery when a visitor opens the affected page.

Weakness
CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Jul 22, 2026 and is one of 11 known issues for this plugin.

Update, patch or deactivate.

Update Ultimate Addons for Elementor to 2.9.2 or later. If an immediate update is impossible, backport the vendor's self-contained hfe_sanitize_icon_html() helper from WordPress Trac changeset 3614409 into inc/js/frontend.js, then pass both toggle_icon and close_icon through that helper before their jQuery .html() calls. Review Navigation Menu widgets edited by untrusted contributors and remove unexpected encoded markup from their toggle and close icon attributes.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The Ultimate Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Navigation Menu Widget data-toggle-icon/data-close-icon Attributes in all versions up to, and including, 2.9.1 due to insufficient input sanitization and output escaping. 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. wp_kses_post, applied on save for users without unfiltered_html, does not neutralize HTML-entity-encoded payloads stored inside data-* attributes on kses-allowed elements, as the browser decodes these values client-side before jQuery .html() renders them as markup.
