CVE-2026-19217 Overview
CVE-2026-19217 is a Stored Cross-Site Scripting (XSS) vulnerability in the Royal Addons for Elementor WordPress plugin in versions before 1.7.1065. The plugin fails to validate a widget setting used to construct an HTML tag before rendering it in output. Authenticated users with Contributor role or higher can inject arbitrary JavaScript that executes in the browsers of visitors and administrators who view the affected content. The flaw is classified under CWE-79: Improper Neutralization of Input During Web Page Generation.
Critical Impact
Contributor-level accounts can inject persistent JavaScript into rendered pages, enabling session theft, administrative account compromise, and drive-by attacks against site visitors.
Affected Products
- Royal Addons for Elementor WordPress plugin versions prior to 1.7.1065
- WordPress sites running the vulnerable plugin with the Elementor page builder
- Any WordPress deployment that grants Contributor or higher roles to untrusted users

Technical Details for CVE-2026-19217
Vulnerability Analysis
The vulnerability resides in a widget provided by the Royal Addons for Elementor plugin. The plugin accepts a widget setting that determines the HTML tag used when rendering widget output. The setting value is written directly into the generated markup without validation against an allow-list of safe tag names or sanitization of attributes.
An attacker with Contributor privileges can supply a crafted value for this setting. The value breaks out of the intended tag context and injects attributes or additional elements containing JavaScript event handlers. When another user renders the page, the browser executes the attacker-controlled script in the site origin.
Because the payload is stored in the WordPress database and served on every page render, the impact scales to all users who view the affected post or page. Administrators who preview or edit the malicious content are prime targets for session hijacking and privilege escalation.
Root Cause
The root cause is missing input validation on a widget-controlled HTML tag name. The plugin trusts editor-supplied data and does not enforce a whitelist of permitted tag values such as h1 through h6, div, or span. WordPress functions like wp_kses() or tag_escape() are not applied before output, allowing the value to be interpreted as arbitrary markup.
Attack Vector
Exploitation requires an authenticated session with at least Contributor privileges and user interaction from a victim who loads the injected page. The attacker edits a post or page, configures the vulnerable Royal Addons widget, and supplies a malicious tag value that closes the intended element and appends an event handler such as onmouseover or onerror. Once the content is saved and rendered, the payload executes in every visitor's browser under the site origin, enabling cookie theft, forced actions via the WordPress REST API, and defacement.

Detection Methods for CVE-2026-19217
Indicators of Compromise
- Unexpected <script> tags, inline event handlers (onerror, onload, onmouseover), or javascript: URIs stored in wp_postmeta entries associated with Elementor data
- Outbound requests from visitor browsers to unfamiliar third-party domains after loading pages built with Royal Addons widgets
- New administrator accounts, altered user roles, or unauthorized changes to plugin settings following Contributor activity
Detection Strategies
- Query the WordPress database for Elementor widget data containing HTML tag settings with non-alphabetic characters, angle brackets, quotes, or the string on followed by an attribute
- Review Contributor and Author activity logs for edits to posts that include Royal Addons widgets
- Deploy web application firewall rules that flag stored content containing script fragments or event handler attributes within widget configuration payloads
Monitoring Recommendations
- Enable and centralize WordPress audit logs to capture post edits, plugin setting changes, and user role modifications
- Monitor Content Security Policy (CSP) violation reports for inline script executions on pages rendered with Royal Addons widgets
- Alert on administrator sessions initiated from unexpected geographies or user agents shortly after Contributor content publication
How to Mitigate CVE-2026-19217
Immediate Actions Required
- Update the Royal Addons for Elementor plugin to version 1.7.1065 or later on all WordPress installations
- Audit existing posts and pages that use Royal Addons widgets for stored payloads and remove or sanitize any suspicious content
- Review Contributor and Author accounts, disable unused accounts, and rotate credentials for any account suspected of misuse
Patch Information
The vendor addressed the issue in Royal Addons for Elementor version 1.7.1065. Site administrators should apply the update through the WordPress plugin dashboard or via WP-CLI. Refer to the WPScan Vulnerability Report for the vendor fix reference.
Workarounds
- Restrict Contributor and Author role assignments to trusted users until patching is complete
- Deploy a Content Security Policy that disallows inline scripts and untrusted event handlers to limit XSS payload execution
- Temporarily deactivate the Royal Addons for Elementor plugin if patching cannot be performed immediately
# Update Royal Addons for Elementor using WP-CLI
wp plugin update royal-elementor-addons --version=1.7.1065
