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. The root cause is improper neutralization of input during web page generation (CWE-79), specifically due to insufficient sanitization and escaping of user-supplied attributes in several of the plugin's widgets. An authenticated attacker with contributor-level privileges or higher can exploit this flaw by injecting malicious JavaScript payloads into pages or posts. These scripts are stored persistently and executed in the context of any user who views the compromised page, potentially leading to session hijacking, privilege escalation, or other malicious actions. The vulnerability has a CVSS v3.1 base score of 6.4, indicating a medium severity level. The attack vector is network-based (remote), requires low attack complexity, and privileges at the contributor level, but no user interaction is needed for the payload to execute once injected. The scope is changed, meaning the vulnerability can affect resources beyond the initially compromised component. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that mitigation may require manual intervention or updates once available. This vulnerability is significant because Elementor is a widely used page builder plugin for WordPress, and LA-Studio Element Kit is a popular add-on, increasing the potential attack surface for websites using these tools.

For European organizations, this vulnerability poses a moderate risk primarily to websites built on WordPress that utilize the Elementor page builder along with the LA-Studio Element Kit plugin. Exploitation could lead to unauthorized script execution in the browsers of site visitors or administrators, potentially resulting in credential theft, unauthorized actions on behalf of users, or defacement. This can damage organizational reputation, lead to data breaches, and disrupt business operations. Given the GDPR regulatory environment in Europe, any compromise involving personal data exposure could result in significant legal and financial penalties. Organizations relying on WordPress for public-facing websites, intranets, or customer portals are particularly at risk. The requirement for contributor-level access means that insider threats or compromised accounts with limited privileges can be leveraged to escalate attacks. The lack of a patch at the time of disclosure increases the window of exposure, necessitating immediate mitigation steps to reduce risk.

European organizations should immediately audit their WordPress installations to identify the presence of the LA-Studio Element Kit plugin and verify its version. Until an official patch is released, the following specific mitigations are recommended: 1) Restrict contributor-level access strictly to trusted users and review user roles and permissions to minimize the number of accounts with such privileges. 2) Implement Web Application Firewall (WAF) rules that detect and block suspicious script injection patterns targeting the vulnerable widgets. 3) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected pages. 4) Monitor website content for unauthorized changes or injected scripts, using automated scanning tools tailored for WordPress environments. 5) Educate content contributors about the risks of injecting untrusted content and enforce strict input validation policies where possible. 6) Prepare for rapid deployment of patches once available by maintaining an up-to-date inventory of affected plugins and a tested update process. 7) Consider temporarily disabling or removing the LA-Studio Element Kit plugin if the risk is deemed unacceptable and no immediate patch is available.
