CVE-2025-54704 is a Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the Easy Elementor Addons plugin developed by hashthemes. This vulnerability arises due to improper neutralization of input during web page generation, specifically enabling DOM-based XSS attacks. DOM-based XSS occurs when client-side scripts write user-controllable data to the Document Object Model (DOM) without proper sanitization or encoding, allowing attackers to execute arbitrary JavaScript in the context of the victim's browser. The affected product versions include all versions up to and including 2.2.6. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be launched remotely over the network with low attack complexity, requires privileges (PR:L) and user interaction (UI:R), and impacts confidentiality, integrity, and availability to a limited extent. The scope is changed (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability allows an attacker with some level of authenticated access to craft malicious payloads that, when executed by other users or themselves, can lead to session hijacking, theft of sensitive information, or execution of unauthorized actions within the context of the affected web application. Since Easy Elementor Addons is a plugin for the Elementor page builder on WordPress, this vulnerability primarily affects websites using this plugin, potentially exposing site visitors and administrators to XSS attacks.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress websites enhanced with the Easy Elementor Addons plugin. Successful exploitation could lead to unauthorized access to user sessions, theft of credentials, or injection of malicious scripts that compromise user trust and data privacy. This is particularly critical for organizations handling sensitive personal data under GDPR regulations, as exploitation could lead to data breaches and subsequent regulatory penalties. Additionally, compromised websites could be used to distribute malware or phishing content, damaging brand reputation and customer confidence. The requirement for some level of privilege and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments where multiple users have editing or administrative roles. The changed scope indicates that the vulnerability could affect other components or users beyond the immediate plugin, potentially amplifying the impact. Given the widespread use of WordPress in Europe across various sectors including e-commerce, media, and public services, the vulnerability poses a tangible risk to operational continuity and data security.

To mitigate this vulnerability, European organizations should first identify all WordPress installations using the Easy Elementor Addons plugin and determine the plugin version. Immediate steps include restricting plugin usage to trusted users with minimal necessary privileges to reduce the risk of exploitation. Since no official patch is currently linked, organizations should monitor vendor communications and security advisories for updates or patches addressing CVE-2025-54704. In the interim, applying Web Application Firewall (WAF) rules that detect and block typical XSS payloads targeting the plugin can reduce exposure. Implementing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts can also mitigate the impact of DOM-based XSS. Regularly auditing and sanitizing user inputs and outputs within the website’s custom code can help prevent injection of malicious scripts. Organizations should also educate users with editing privileges about the risks of interacting with untrusted content and the importance of cautious behavior when clicking links or opening content within the site. Finally, maintaining comprehensive logging and monitoring for unusual activities related to the plugin can facilitate early detection of exploitation attempts.
