CVE-2026-19226 Overview
CVE-2026-19226 is a Stored Cross-Site Scripting (XSS) vulnerability in the Royal Addons for Elementor WordPress plugin versions prior to 1.7.1066. The plugin fails to validate certain widget settings before rendering them inside HTML attributes. Authenticated users with the Contributor role or above can inject malicious JavaScript that executes in the browsers of other users who view the affected content. The flaw is categorized under CWE-79 (Improper Neutralization of Input During Web Page Generation).
Critical Impact
Contributor-level users can persist malicious scripts that execute in higher-privileged users' browsers, enabling session theft, administrative action abuse, and site takeover.
Affected Products
- Royal Addons for Elementor WordPress plugin versions before 1.7.1066
- WordPress sites permitting Contributor role or higher content submission
- Elementor-based sites deploying Royal Addons widgets

Technical Details for CVE-2026-19226
Vulnerability Analysis
The vulnerability resides in how Royal Addons for Elementor processes widget configuration values before emitting them into rendered HTML. Widget settings supplied by an authenticated user are inserted into HTML attributes without sufficient contextual encoding. An attacker with Contributor privileges can craft settings containing attribute-breaking payloads that terminate the intended attribute and introduce arbitrary event handlers. The malicious markup is persisted in the post or page, resulting in stored execution whenever the content is rendered. Because payloads execute in the context of viewers, including Editors and Administrators, the impact extends well beyond the Contributor account used to plant them.
Root Cause
The underlying defect is missing validation and attribute-context output encoding on selected widget setting fields. The plugin trusts values submitted through the Elementor editor and outputs them directly into HTML attribute contexts. Attribute-context sinks require encoding of quotes and angle brackets in addition to standard HTML entity encoding, which the vulnerable code paths omit.
Attack Vector
Exploitation requires an authenticated session with Contributor role or higher and user interaction from a victim viewing the affected content. The attacker edits a page or post that uses a vulnerable Royal Addons widget and supplies a crafted value in the exposed setting. The payload closes the surrounding attribute and injects a JavaScript event handler. When any user later loads the page, the browser executes the attacker-controlled script under the site origin, allowing cookie access, DOM manipulation, and requests authenticated as the victim. Refer to the WPScan Vulnerability Report for additional technical detail.
Detection Methods for CVE-2026-19226
Indicators of Compromise
- Widget setting values in wp_postmeta containing onerror=, onload=, onmouseover=, or javascript: sequences.
- Unexpected <script> fragments or attribute-breaking quote characters stored inside Elementor _elementor_data meta fields.
- New or unfamiliar Contributor accounts creating or editing posts that use Royal Addons widgets.
Detection Strategies
- Audit posts and revisions authored by Contributor-role accounts for HTML attribute anomalies within Royal Addons widget JSON.
- Search database exports for encoded payload markers such as \" or \\u003e adjacent to Royal Addons widget identifiers.
- Monitor outbound requests from browsers loading affected pages for unusual beacons to attacker-controlled domains.
Monitoring Recommendations
- Enable WordPress activity logging to capture post edits, revisions, and user role assignments.
- Deploy Content Security Policy (CSP) reporting to identify inline script violations on Elementor-rendered pages.
- Alert on privilege changes that elevate Contributor accounts to Author, Editor, or Administrator following recent post activity.
How to Mitigate CVE-2026-19226
Immediate Actions Required
- Update Royal Addons for Elementor to version 1.7.1066 or later on all WordPress installations.
- Review the Contributor and Author user list and remove accounts that are unused or unrecognized.
- Inspect existing posts and pages built with Royal Addons widgets for suspicious script content and revert affected revisions.
Patch Information
The plugin vendor addressed the vulnerability in Royal Addons for Elementor version 1.7.1066 by adding validation and encoding for widget settings written into HTML attribute contexts. Site administrators should apply the update through the WordPress plugin manager or by installing the packaged release. Confirm the installed version reports 1.7.1066 or higher after the update completes.
Workarounds
- Restrict the Contributor role temporarily and require Editor review before publishing posts that include Royal Addons widgets.
- Disable the Royal Addons for Elementor plugin until the patch is applied if immediate updating is not feasible.
- Apply a Web Application Firewall (WAF) rule that blocks attribute-breaking payloads in POST requests to /wp-admin/admin-ajax.php targeting Elementor endpoints.
# Update the plugin via WP-CLI
wp plugin update royal-elementor-addons --version=1.7.1066
wp plugin get royal-elementor-addons --field=version
