CVE-2025-64361 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in the StylemixThemes Consulting Elementor Widgets plugin for WordPress, specifically affecting versions up to 1.4.2. The vulnerability stems from improper neutralization of input during the generation of web pages, allowing malicious scripts to be injected into the Document Object Model (DOM) on the client side. Unlike reflected or stored XSS, DOM-based XSS occurs entirely in the browser, exploiting client-side code that processes untrusted input insecurely. Attackers can craft URLs or input fields that, when processed by the vulnerable widget, execute arbitrary JavaScript in the context of the victim's browser session. This can lead to session hijacking, theft of sensitive data such as cookies or credentials, unauthorized actions on behalf of users, or website defacement. The plugin is widely used in consulting and business websites built with Elementor, a popular WordPress page builder, increasing the potential attack surface. No authentication is required for exploitation, and user interaction is limited to visiting a maliciously crafted link or page. Although no public exploits are reported yet, the vulnerability's nature and the plugin's popularity make it a credible threat. The lack of a CVSS score necessitates an assessment based on impact and exploitability factors. The vulnerability affects the confidentiality and integrity of user data and website content, with moderate impact on availability. The scope is broad due to the plugin's usage in many WordPress sites, especially in Europe where WordPress market penetration is high. The vulnerability was published on October 31, 2025, by Patchstack, with no patch links currently available, indicating that remediation may be pending. Organizations using this plugin should monitor for updates and apply mitigations proactively.

For European organizations, the impact of CVE-2025-64361 can be significant, particularly for businesses relying on WordPress sites with the Consulting Elementor Widgets plugin for client engagement, marketing, or service delivery. Successful exploitation can lead to unauthorized access to user sessions, exposing personal data and credentials, which may violate GDPR and other data protection regulations, resulting in legal and financial penalties. The integrity of website content can be compromised, damaging brand reputation and customer trust. Attackers could also use the vulnerability as a foothold for further attacks, such as phishing or malware distribution. Given the plugin's use in consulting and professional services sectors, which are prevalent in Europe, the threat could disrupt critical business operations and client communications. Additionally, the vulnerability could be leveraged in targeted attacks against high-value organizations or government entities using the plugin, amplifying the risk. The absence of a patch at the time of disclosure increases the window of exposure, necessitating immediate compensating controls. Overall, the vulnerability poses a high risk to confidentiality and integrity, with moderate availability impact, making it a priority for European cybersecurity teams.

1. Monitor the vendor's official channels and Patchstack for the release of a security patch addressing CVE-2025-64361 and apply it immediately upon availability. 2. Until a patch is available, implement strict Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the risk of DOM-based XSS exploitation. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the vulnerable plugin's input vectors. 4. Conduct a thorough audit of all user inputs processed by the Consulting Elementor Widgets plugin and apply additional server-side sanitization and validation where possible. 5. Educate website administrators and developers about the risks of DOM-based XSS and encourage the use of secure coding practices in custom Elementor widgets or extensions. 6. Limit the exposure of the affected plugin by disabling or removing unused widgets and features within Elementor that rely on the vulnerable plugin. 7. Regularly review access logs and monitor for unusual activity or signs of exploitation attempts targeting the plugin. 8. For organizations with high-risk profiles, consider isolating affected web applications or deploying virtual patching solutions until official fixes are deployed.
