CVE-2025-3076 is a stored cross-site scripting vulnerability classified under CWE-79, affecting the Elementor Website Builder Pro plugin for WordPress in all versions up to and including 3.29.0. The vulnerability stems from insufficient sanitization and escaping of the 'button_text' parameter, which is used during web page generation. Authenticated attackers with Contributor-level privileges or higher can exploit this flaw by injecting arbitrary JavaScript code into the 'button_text' field. Because the injected script is stored persistently within the website content, it executes in the context of any user who visits the infected page, including administrators and other privileged users. This can lead to theft of session cookies, unauthorized actions, or further compromise of the website and its users. The vulnerability requires no user interaction beyond page access but does require the attacker to have authenticated access with at least Contributor privileges, which are commonly granted to content creators or editors. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required but no user interaction. No public exploits have been reported yet, but the widespread use of Elementor Pro in WordPress sites makes this a significant concern. The vulnerability highlights the importance of proper input validation and output encoding in web applications, especially those that allow user-generated content to be rendered dynamically.

The impact of CVE-2025-3076 is significant for organizations using Elementor Website Builder Pro, as it allows authenticated users with relatively low privileges to execute arbitrary JavaScript in the context of the website. This can lead to session hijacking, defacement, unauthorized actions, or the spread of malware to site visitors. For organizations relying on WordPress and Elementor Pro for their public-facing websites, this vulnerability can compromise the integrity and confidentiality of user data and damage organizational reputation. Attackers could leverage this flaw to escalate privileges, steal sensitive information, or disrupt business operations by injecting malicious scripts. Since the vulnerability affects all versions up to 3.29.0, a large number of websites remain exposed. The requirement for authenticated access limits the attack surface but does not eliminate risk, especially in environments with multiple contributors or editors. The vulnerability also poses risks to end users who may unknowingly execute malicious scripts, leading to broader security implications beyond the website itself.

To mitigate CVE-2025-3076, organizations should immediately update Elementor Website Builder Pro to a patched version once available. Until a patch is released, administrators should restrict Contributor-level and higher privileges to trusted users only, minimizing the risk of malicious script injection. Implement strict role-based access controls and regularly audit user permissions to ensure no unnecessary privileges are granted. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the 'button_text' parameter. Enable Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on the website. Regularly scan website content for injected scripts or anomalies using security plugins or external tools. Educate content creators about the risks of injecting untrusted content and enforce input validation on all user-submitted data. Monitor logs for unusual activities related to page content modifications. Finally, maintain regular backups of website data to enable quick restoration in case of compromise.
