CVE-2025-8360 is a stored Cross-Site Scripting (XSS) vulnerability affecting the LA-Studio Element Kit for Elementor WordPress plugin, developed by choijun. This vulnerability exists in all versions up to and including 1.5.5.1 due to improper neutralization of user-supplied input during web page generation. Specifically, several widgets within the plugin fail to adequately sanitize and escape input attributes, allowing an authenticated attacker with contributor-level privileges or higher to inject arbitrary JavaScript code into pages. When other users visit these compromised pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions within the context of the affected website. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and has a CVSS v3.1 base score of 6.4, indicating a medium severity level. The attack vector is network-based, with low attack complexity, requiring privileges equivalent to contributor access, and no user interaction is needed for exploitation. The scope is changed, meaning the vulnerability can affect resources beyond the initially compromised component, and the impact affects confidentiality and integrity but not availability. No known exploits have been reported in the wild as of the publication date (September 6, 2025), and no official patches have been linked yet. This vulnerability is significant because WordPress is widely used across Europe, and Elementor is a popular page builder plugin, making this a relevant threat to many websites that rely on these tools for content management and presentation.

For European organizations, this vulnerability poses a moderate risk primarily to websites using WordPress with the LA-Studio Element Kit for Elementor plugin. The ability for an authenticated contributor to inject persistent malicious scripts can lead to unauthorized data disclosure, session hijacking, or manipulation of website content, undermining user trust and potentially exposing sensitive customer or employee information. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations if personal data is compromised), and financial losses. Since contributors typically have limited privileges, the attack surface is somewhat restricted, but insider threats or compromised contributor accounts could be leveraged by attackers. Additionally, the cross-site scripting vulnerability could be used as a pivot point for further attacks, such as delivering malware or phishing campaigns targeting site administrators or visitors. The lack of a patch at the time of disclosure means organizations must rely on mitigation strategies to reduce risk. Given the widespread use of WordPress and Elementor in Europe, especially among SMEs and digital agencies, the impact could be broad if not addressed promptly.

1. Immediate mitigation should include restricting contributor-level access to trusted users only and monitoring for unusual activity or content changes within the affected widgets. 2. Implement Web Application Firewall (WAF) rules specifically targeting known XSS payload patterns related to this vulnerability to block malicious requests. 3. Disable or remove the LA-Studio Element Kit for Elementor plugin if it is not essential or replace it with alternative, secure plugins. 4. Regularly audit and sanitize all user-generated content manually or via automated tools to detect and remove injected scripts. 5. Enforce strict Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected websites. 6. Monitor official vendor channels and security advisories for patches or updates and apply them promptly once available. 7. Conduct security awareness training for contributors to recognize phishing or social engineering attempts that could lead to account compromise. 8. Use multi-factor authentication (MFA) for all WordPress accounts to reduce the risk of unauthorized access. These measures go beyond generic advice by focusing on access control, content monitoring, and layered defenses tailored to the specific nature of this stored XSS vulnerability.
