CVE-2026-107098 in Addons for Elementor Plugin
Summary
by MITRE • 10/28/2026
The Royal Addons for Elementor WordPress plugin before 1.7.1070 does not sanitise and escape one of its map widget's size settings before concatenating it into an HTML attribute, allowing users with the Contributor role or above to inject JavaScript that runs in the browser of any user who views the page, including an administrator reviewing a pending submission.

The vulnerability identified in Royal Addons for Elementor prior to version 1.7.1070 represents a classic Stored Cross-Site Scripting flaw rooted in insufficient input validation and output encoding mechanisms within the plugin's map widget functionality. Specifically, the defect lies in how size settings associated with map widgets are processed before being rendered into HTML attributes. The software fails to properly sanitize user-supplied data or escape special characters that have semantic meaning in HTML contexts, such as angle brackets, quotes, and ampersands. This lack of rigorous filtering allows malicious actors to inject arbitrary JavaScript code directly into the widget's configuration parameters. Because this data is stored within the WordPress database and subsequently rendered on public-facing pages without adequate protection, it persists across sessions and user interactions, creating a persistent threat vector rather than a transient session-based issue.
The operational impact of this vulnerability is significant due to the relatively low privilege threshold required for exploitation. Users possessing at least the Contributor role or higher can trigger the injection by modifying widget settings during content creation or editing processes. This accessibility makes it feasible for compromised accounts, disgruntled employees with legitimate access, or social engineering targets to execute attacks without needing administrative credentials initially. The most critical consequence arises when an administrator views a page containing the malicious payload, particularly if they are reviewing pending submissions from contributors. In such scenarios, the injected JavaScript executes within the context of the administrator's authenticated session in their browser. This enables attackers to perform actions on behalf of the admin, steal sensitive cookies or session tokens that facilitate persistent access, exfiltrate data visible only to administrators, or redirect users to phishing sites designed to harvest credentials.
From a technical classification perspective, this vulnerability aligns with CWE-79, which denotes Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. The specific mechanism involves the failure to escape output in an HTML attribute context, falling under sub-categories that address improper encoding or escaping of data before insertion into web pages. Furthermore, within the MITRE ATT&CK framework for enterprise security, this behavior maps directly to T1059.007, which covers JavaScript as a client-side script execution technique. The attack chain typically involves Initial Access through low-privileged user accounts, followed by Execution via browser-based scripting, and potentially Persistence if session tokens are harvested or backdoors are installed using the elevated privileges gained from compromising an administrator account.
Mitigation strategies must address both immediate remediation and long-term defensive posture improvements. The primary and most effective solution is to upgrade the Royal Addons for Elementor plugin to version 1.7.1070 or later, where these sanitization and escaping routines have been corrected by the developers. For organizations unable to patch immediately due to compatibility concerns with other plugins, temporary workarounds include restricting the Contributor role's ability to edit widget settings if possible through custom code snippets that override default capabilities, although this may impact workflow efficiency. Additionally, implementing a Content Security Policy header can help mitigate the impact of successful XSS attacks by restricting the sources from which scripts are allowed to execute, thereby preventing many types of injected payloads from running even if they are successfully stored in the database. Regular security audits and code reviews focusing on input validation and output encoding practices should be integrated into the development lifecycle to prevent similar vulnerabilities in future updates or custom integrations.
