CVE-2025-14274 is a stored Cross-Site Scripting vulnerability identified in the Unlimited Elements for Elementor plugin for WordPress, specifically in the Border Hero widget's Button Link field. The vulnerability stems from insufficient sanitization and escaping of user-supplied URLs, allowing authenticated users with Contributor-level access or higher to inject arbitrary JavaScript code into pages. When other users visit these pages, the malicious scripts execute in their browsers, potentially compromising session tokens, redirecting users, or performing actions on behalf of the victim. The vulnerability affects all versions up to 2.0.1 of the plugin. The CVSS 3.1 base score is 5.4 (medium), reflecting network attack vector, low attack complexity, requiring privileges (Contributor or above), and user interaction (visiting the infected page). The scope is changed as the vulnerability affects components beyond the initially vulnerable code, impacting the confidentiality and integrity of user data but not availability. No patches or official fixes have been published yet, and no known exploits are reported in the wild. The vulnerability is categorized under CWE-79, which covers improper neutralization of input during web page generation. This vulnerability is particularly concerning in multi-user WordPress environments where contributors can add content but are not fully trusted. Attackers can leverage this to escalate privileges or conduct phishing and session hijacking attacks within the site context.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of user data and site content. Attackers with contributor access can inject malicious scripts that execute in the browsers of site visitors, potentially leading to session hijacking, theft of sensitive information, or unauthorized actions performed on behalf of users. This can damage organizational reputation, lead to data breaches, and cause compliance issues under GDPR due to unauthorized data exposure. The impact is heightened in organizations with multiple content contributors or where contributor accounts are less strictly managed. Since the vulnerability requires authentication and user interaction, the risk is somewhat mitigated but still significant in collaborative environments. Additionally, compromised sites can be used as platforms for broader phishing or malware distribution campaigns targeting European users. The absence of patches increases the urgency for interim mitigations. Organizations relying heavily on WordPress for public-facing websites, especially those using the Unlimited Elements for Elementor plugin, should consider this a priority threat.

1. Immediately audit and restrict Contributor-level user permissions to only trusted individuals, minimizing the risk of malicious script injection. 2. Implement strict input validation and output encoding on all user-supplied data fields, especially the Button Link field in the Border Hero widget, to prevent script injection. 3. Monitor website content and logs for unusual or suspicious script injections or modifications. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting this plugin. 5. Educate content contributors about the risks of injecting untrusted URLs or scripts. 6. Regularly back up website data to enable quick restoration if compromise occurs. 7. Follow the plugin vendor’s updates closely and apply patches immediately once available. 8. Consider temporarily disabling or replacing the vulnerable widget or plugin until a fix is released. 9. Use Content Security Policy (CSP) headers to restrict execution of unauthorized scripts on the website. 10. Conduct periodic security assessments focusing on user-generated content areas to detect similar vulnerabilities.
