CVE-2025-62887 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the King Addons for Elementor WordPress plugin, specifically versions up to 51.1.37. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious scripts to be injected and executed in the victim’s browser context. The attack vector is remote network access (AV:N), with low attack complexity (AC:L), requiring low privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the initially vulnerable component. The impact includes partial confidentiality and integrity loss (C:L/I:L) but no availability impact (A:N). The vulnerability is DOM-based, meaning the malicious payload is executed as a result of client-side script processing unsafe input, often via URL parameters or other client-controllable data. Exploitation typically involves tricking an authenticated user into clicking a crafted link or interacting with malicious content, enabling attackers to steal session tokens, perform unauthorized actions, or manipulate displayed content. No public exploits have been reported yet, and no patches are currently linked, indicating the need for vigilance and prompt patch application once available. The vulnerability affects a widely used WordPress plugin that extends Elementor page builder capabilities, which is popular among European websites for content management and customization.

For European organizations, this vulnerability poses a moderate risk primarily to websites and web applications using the King Addons for Elementor plugin. Successful exploitation can lead to session hijacking, unauthorized actions performed on behalf of users, and potential leakage of sensitive information. This can undermine user trust, lead to data breaches, and damage organizational reputation. Given the widespread use of WordPress and Elementor in Europe, especially among SMEs and digital service providers, the attack surface is significant. The requirement for authenticated access and user interaction limits the ease of exploitation but does not eliminate risk, particularly in environments with many users or where social engineering is feasible. The vulnerability does not impact system availability directly but can facilitate further attacks or unauthorized access, compounding risks. Organizations handling personal data under GDPR must consider the compliance implications of such a vulnerability if exploited.

Organizations should monitor KingAddons.com for official patches addressing CVE-2025-62887 and apply updates promptly once released. Until patches are available, restrict plugin usage to trusted users with minimal privileges and review user roles to limit exposure. Implement Content Security Policy (CSP) headers to reduce the impact of injected scripts by restricting sources of executable scripts. Conduct regular security audits of WordPress plugins and configurations to identify and remediate unsafe input handling. Educate users about phishing and social engineering risks to reduce the likelihood of malicious link interaction. Consider deploying Web Application Firewalls (WAF) with rules targeting XSS attack patterns to provide additional protection. Backup website data regularly to enable recovery in case of compromise. Finally, monitor logs for unusual activity that may indicate attempted exploitation.
