CVE-2025-64361 is a medium-severity DOM-based Cross-site Scripting (XSS) vulnerability found in the StylemixThemes Consulting Elementor Widgets WordPress plugin, specifically affecting versions up to and including 1.4.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be injected into the Document Object Model (DOM). This form of XSS is client-side and occurs when untrusted data is processed by client-side scripts without proper sanitization or encoding, enabling attackers to execute arbitrary JavaScript in the context of the victim's browser. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates that the attack can be launched remotely over the network with low attack complexity, requires low privileges (authenticated user), and user interaction (such as clicking a crafted link). The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable module. The impact includes partial loss of confidentiality, integrity, and availability, as attackers could steal session tokens, manipulate page content, or perform actions on behalf of the user. No known exploits have been reported in the wild yet, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is commonly used in WordPress sites that utilize Elementor page builder for consulting or business themes, making it a relevant target for attackers aiming to compromise such websites.

For European organizations, this vulnerability poses a risk primarily to websites running WordPress with the Consulting Elementor Widgets plugin by StylemixThemes. Successful exploitation could lead to session hijacking, unauthorized actions on behalf of users, defacement, or redirection to malicious sites, impacting the confidentiality and integrity of user data and potentially causing reputational damage. Organizations in sectors such as consulting, professional services, and business development that rely on this plugin for their web presence are particularly at risk. The medium severity and requirement for user interaction reduce the likelihood of widespread automated exploitation but do not eliminate targeted attacks. Additionally, compromised websites could be used as a vector for further attacks against visitors or internal networks, increasing the overall risk posture. The impact on availability is limited but possible if attackers inject disruptive scripts. Given the interconnected nature of European digital services and the importance of trust in online business platforms, this vulnerability could have cascading effects if exploited at scale.

1. Monitor official StylemixThemes channels and WordPress plugin repositories for patches addressing CVE-2025-64361 and apply updates immediately upon release. 2. Until a patch is available, consider disabling or removing the Consulting Elementor Widgets plugin if feasible, especially on high-risk or critical sites. 3. Implement strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts and reduce the impact of DOM-based XSS. 4. Employ Web Application Firewalls (WAFs) with rules tailored to detect and block typical XSS payloads targeting Elementor widgets. 5. Conduct thorough input validation and output encoding on any custom code interacting with the plugin or user inputs to prevent injection. 6. Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content that could trigger the XSS. 7. Regularly audit website logs and monitor for unusual activity indicative of exploitation attempts. 8. Consider isolating critical web assets and limiting plugin usage to reduce the attack surface. 9. Use security plugins that can detect and remediate XSS vulnerabilities or suspicious DOM manipulations in real time.
