CVE-2025-7440 is a stored Cross-Site Scripting (XSS) vulnerability identified in the yeashir Anber Elementor Addon plugin for WordPress, affecting all versions up to and including 1.0.1. The vulnerability arises due to improper neutralization of input during web page generation, specifically through insufficient sanitization and output escaping of the $item['button_link']['url'] parameter. This flaw allows an authenticated attacker with Contributor-level privileges or higher to inject arbitrary malicious scripts into pages generated by the plugin. When other users visit these compromised pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, defacement, or distribution of malware. The vulnerability is classified under CWE-79, indicating a failure to properly sanitize input before rendering it in a web context. The CVSS v3.1 base score is 6.4 (medium severity), with an attack vector of network (remote exploitation), low attack complexity, requiring privileges (PR:L) but no user interaction, and impacting confidentiality and integrity with a scope change. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects a widely used WordPress plugin that integrates with Elementor, a popular page builder, increasing the potential attack surface for websites using this plugin.

For European organizations, this vulnerability poses a significant risk especially to those relying on WordPress websites enhanced with the Anber Elementor Addon plugin. Exploitation could lead to unauthorized script execution in the context of the victim's browser, enabling attackers to steal session cookies, perform actions on behalf of users, or deliver further malware payloads. This can compromise user data confidentiality and website integrity, potentially damaging brand reputation and violating data protection regulations such as GDPR. Since the vulnerability requires authenticated access at Contributor level or higher, organizations with multiple content editors or contributors are at increased risk. The scope change in the CVSS vector indicates that the vulnerability could affect resources beyond the initially vulnerable component, amplifying the impact. Given the widespread use of WordPress across European businesses, including e-commerce, government, and media sectors, the threat could disrupt services and lead to data breaches if exploited.

To mitigate this vulnerability, European organizations should: 1) Immediately audit their WordPress installations to identify the presence of the Anber Elementor Addon plugin and verify its version. 2) Restrict Contributor-level access strictly to trusted users and review user roles and permissions to minimize exposure. 3) Implement web application firewalls (WAFs) with rules to detect and block malicious payloads targeting the vulnerable parameter. 4) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 5) Monitor website logs for unusual activity indicative of attempted exploitation. 6) Since no official patch is currently available, consider temporarily disabling the plugin or removing the vulnerable functionality until a fix is released. 7) Educate content contributors about safe input practices and the risks of injecting untrusted content. 8) Plan for rapid deployment of patches once released by the vendor. These steps go beyond generic advice by focusing on access control, proactive detection, and containment strategies tailored to the vulnerability's characteristics.
