CVE-2025-62887 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the King Addons for Elementor plugin developed by KingAddons.com, affecting all versions up to and including 51.1.37. The vulnerability stems from improper neutralization of user input during the generation of web pages, which allows attackers to inject malicious scripts into the DOM. Unlike traditional reflected or stored XSS, DOM-based XSS occurs entirely on the client side, where the malicious payload manipulates the Document Object Model after the page has loaded, often bypassing server-side sanitization. This can lead to execution of arbitrary JavaScript in the context of the victim’s browser session. Potential attack vectors include crafted URLs or manipulated input fields that the plugin processes insecurely. Exploitation can result in theft of cookies, session tokens, or other sensitive information, as well as unauthorized actions such as changing user settings or performing transactions. The vulnerability affects websites using the King Addons for Elementor plugin, a popular extension for the Elementor page builder on WordPress, widely used for enhancing site functionality and design. No official patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved and published in late October 2025 by Patchstack, but lacks a CVSS score, indicating it may be newly disclosed. Due to the nature of DOM-based XSS, exploitation requires user interaction, typically by convincing a user to visit a maliciously crafted URL or interact with malicious content. The plugin’s widespread use in WordPress sites, especially in Europe, increases the risk surface. Organizations relying on this plugin for their web presence should be aware of the risk and prepare to deploy fixes promptly once available.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of user data and web sessions. Exploitation could lead to credential theft, session hijacking, and unauthorized actions performed on behalf of legitimate users, potentially resulting in data breaches, financial fraud, or reputational damage. Organizations in sectors such as e-commerce, finance, healthcare, and government services that rely on WordPress sites with King Addons for Elementor are particularly vulnerable. The vulnerability could also be leveraged as a foothold for further attacks within corporate networks if attackers gain access through compromised user accounts. Given the plugin’s role in enhancing website functionality, exploitation might disrupt normal operations or degrade user trust. The lack of current known exploits provides a window for proactive mitigation, but the ease of exploitation through social engineering or malicious links means the threat could escalate rapidly once weaponized. European privacy regulations such as GDPR increase the stakes, as data breaches resulting from such vulnerabilities can lead to significant fines and legal consequences.

1. Monitor official KingAddons.com channels and Patchstack advisories for the release of security patches addressing CVE-2025-62887 and apply them immediately upon availability. 2. Implement strict input validation and sanitization on all user-supplied data processed by the website, especially inputs handled by the King Addons plugin. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content that could trigger DOM-based XSS. 5. Conduct regular security audits and penetration testing focused on client-side vulnerabilities, including DOM-based XSS. 6. Use Web Application Firewalls (WAFs) with rules designed to detect and block XSS attack patterns targeting WordPress plugins. 7. Limit plugin usage to only those necessary and keep all WordPress components updated to minimize attack surface. 8. Implement multi-factor authentication (MFA) to reduce the impact of credential theft resulting from XSS exploitation. 9. Monitor web server and application logs for unusual activity that may indicate exploitation attempts. 10. Consider isolating critical web applications or sensitive user interactions from plugins with known vulnerabilities until patched.
