CVE-2025-6251 identifies a stored cross-site scripting (XSS) vulnerability in the Royal Addons for Elementor – Addons and Templates Kit for Elementor WordPress plugin, maintained by wproyal. The vulnerability arises from improper neutralization of input during web page generation, specifically through the $item['field_id'] parameter. All plugin versions up to and including 1.7.1036 are affected. The root cause is insufficient sanitization and escaping of user-supplied input before it is embedded into web pages, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary JavaScript code. This malicious code is stored persistently and executed in the browsers of any users who visit the affected pages, enabling attacks such as session hijacking, privilege escalation, defacement, or distribution of malware. The vulnerability requires authentication but no additional user interaction for exploitation. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) reflects network attack vector, low attack complexity, low privileges required, no user interaction, scope change, and partial impact on confidentiality and integrity but no impact on availability. No public exploits have been reported yet, but the vulnerability poses a significant risk given the popularity of Elementor and its addons in WordPress ecosystems.

The vulnerability allows attackers with Contributor-level access to inject persistent malicious scripts into WordPress sites using the affected plugin. This can lead to unauthorized actions such as stealing user credentials or session cookies, defacing websites, redirecting visitors to malicious sites, or conducting further attacks within the affected environment. Since the injected scripts execute in the context of the victim’s browser, the confidentiality and integrity of user data can be compromised. Organizations relying on this plugin for website functionality risk reputational damage, data breaches, and potential regulatory consequences if user data is exposed. The scope of impact is significant due to the widespread use of Elementor and its addons in diverse sectors including e-commerce, media, education, and government websites worldwide. Although exploitation requires authenticated access, many WordPress sites allow user registrations or have multiple contributors, increasing the attack surface. The vulnerability does not affect availability directly but can indirectly cause service disruptions through defacement or administrative lockout.

1. Immediately update the Royal Addons for Elementor plugin to a patched version once released by the vendor. Monitor official channels for patch announcements. 2. Until a patch is available, restrict Contributor-level and higher permissions to trusted users only, minimizing the risk of malicious input injection. 3. Implement a Web Application Firewall (WAF) with custom rules to detect and block suspicious script injections targeting the $item['field_id'] parameter or similar inputs. 4. Conduct regular security audits of user-generated content and sanitize inputs manually if possible. 5. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 6. Educate site administrators and contributors about the risks of XSS and safe content practices. 7. Monitor logs and user activity for unusual behavior indicative of exploitation attempts. 8. Consider disabling or limiting the use of the vulnerable plugin if immediate patching is not feasible, especially on high-value or public-facing sites.
