CVE-2025-6229 is a stored Cross-Site Scripting vulnerability identified in the Sina Extension for Elementor, a popular WordPress plugin that provides various widgets and templates including Header Builder, Footer Builder, Theme Builder, Slider, Gallery, Form, Modal, and Data Table Free Elementor Widgets. The vulnerability specifically affects the Fancy Text Widget and Countdown Widget DOM attributes due to improper neutralization of input during web page generation, classified under CWE-79. This improper input sanitization and lack of output escaping allow authenticated attackers with Contributor-level privileges or higher to inject arbitrary JavaScript code into pages. When other users access these pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, defacement, or unauthorized actions within the context of the victim’s session. The vulnerability affects all versions up to and including 3.7.0 of the plugin. The attack vector is network-based with low attack complexity, requiring privileges but no user interaction. The vulnerability impacts confidentiality and integrity but not availability, and the scope is changed as the vulnerability can affect other users viewing the injected content. No patches or known exploits have been reported at the time of publication. The CVSS 3.1 score of 6.4 reflects a medium severity level, emphasizing the need for remediation in environments where this plugin is deployed.

The primary impact of CVE-2025-6229 is the potential compromise of user confidentiality and integrity on WordPress sites using the vulnerable Sina Extension for Elementor plugin. Attackers with Contributor-level access can inject malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to session hijacking, theft of sensitive information, unauthorized actions on behalf of users, or defacement of site content. While availability is not directly affected, the reputational damage and trust loss from such attacks can be significant. Organizations running WordPress sites with this plugin, especially those with multiple contributors or user-generated content, face increased risk of persistent XSS attacks. This can facilitate further attacks such as privilege escalation or malware distribution. The vulnerability’s requirement for authenticated access limits exposure but does not eliminate risk in environments with multiple contributors or compromised accounts. Without mitigation, attackers can exploit this vulnerability to undermine site security and user trust globally.

To mitigate CVE-2025-6229, organizations should first verify if they are using the Sina Extension for Elementor plugin and identify the version in use. Since no official patches are currently available, immediate mitigation includes restricting Contributor-level and higher privileges to trusted users only, minimizing the risk of malicious script injection. Administrators should audit existing content created via the Fancy Text Widget and Countdown Widget for suspicious or unauthorized scripts and remove any malicious code found. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads can provide an additional layer of defense. Site owners should monitor plugin updates closely and apply security patches promptly once released by the vendor. Additionally, employing Content Security Policy (CSP) headers can help limit the impact of injected scripts by restricting script execution sources. Regular security training for contributors to avoid unsafe input practices and maintaining least privilege principles will further reduce exploitation likelihood.
