CVE-2025-62887 is a DOM-based Cross-site Scripting (XSS) vulnerability found in KingAddons.com King Addons for Elementor, a popular WordPress plugin that extends Elementor page builder functionality. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be injected and executed in the context of the victim's browser. This type of XSS is client-side, meaning the attack payload is executed within the Document Object Model (DOM) without necessarily involving server-side script injection. The affected versions include all releases up to and including 51.1.37. The CVSS v3.1 base score is 5.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact affects confidentiality and integrity but not availability. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly. This vulnerability could allow attackers to steal session cookies, perform actions on behalf of users, or manipulate page content, leading to potential data breaches or reputational damage.

For European organizations, this vulnerability poses a risk primarily to websites using WordPress with the King Addons for Elementor plugin. Successful exploitation could lead to session hijacking, unauthorized actions performed under the victim's credentials, theft of sensitive information, or defacement of web content. This can damage the organization's reputation, lead to regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and cause financial losses. Since Elementor and its addons are widely used for website customization, especially in SMEs and digital agencies, the attack surface is significant. The requirement for user interaction limits automated mass exploitation, but targeted phishing or social engineering campaigns could increase risk. The medium severity suggests moderate urgency but does not imply immediate critical threat. However, unpatched sites remain vulnerable to emerging exploit techniques.

1. Monitor KingAddons.com and official plugin repositories for security patches addressing CVE-2025-62887 and apply updates immediately upon release. 2. Until patches are available, implement strict input validation and output encoding on all user-controllable inputs processed by the plugin or site to prevent script injection. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. 4. Conduct regular security audits and penetration testing focusing on client-side vulnerabilities in WordPress plugins. 5. Educate users and administrators about the risks of clicking suspicious links or interacting with untrusted content to mitigate social engineering vectors. 6. Consider temporarily disabling or replacing the vulnerable plugin if patching is delayed and the risk is unacceptable. 7. Use web application firewalls (WAFs) with rules targeting XSS attack patterns to provide an additional layer of defense.
