CVE-2025-64355 is a DOM-based Cross-site Scripting (XSS) vulnerability classified under CWE-79, found in the Crocoblock JetElements plugin for Elementor, a popular WordPress page builder. The vulnerability exists due to improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be injected and executed within the victim's browser context. This can lead to unauthorized actions such as session hijacking, defacement, or redirection to malicious sites. The affected versions include all releases up to 2.7.12, with no specific version range provided. The vulnerability requires network access (AV:N), low attack complexity (AC:L), privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability losses, as reflected in the CVSS 3.1 score of 6.5 (medium). No patches or known exploits are currently available, but the vulnerability's presence in a widely used plugin increases the risk of future exploitation. The vulnerability is particularly relevant for websites that rely on JetElements for dynamic content generation, as attackers can craft malicious payloads to exploit this flaw via user input fields or URL parameters that are improperly sanitized.

For European organizations, this vulnerability can lead to significant security risks, especially for those operating public-facing websites using WordPress with the JetElements plugin. Successful exploitation could result in unauthorized script execution in users' browsers, potentially leading to session hijacking, theft of sensitive information, defacement, or distribution of malware. This undermines user trust and can cause reputational damage, regulatory non-compliance (e.g., GDPR breaches due to data exposure), and financial losses. The medium severity rating indicates a moderate but tangible risk, particularly for sectors like e-commerce, finance, healthcare, and government services that rely heavily on web presence. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure victims. The lack of available patches means organizations must proactively implement mitigations to reduce exposure until fixes are released.

1. Monitor Crocoblock and Elementor official channels for security updates and apply patches immediately once available. 2. Implement strict input validation and sanitization on all user-controllable inputs, especially those rendered by JetElements components. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. Use Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting JetElements. 5. Educate users and administrators about phishing and social engineering risks that could facilitate exploitation. 6. Conduct regular security audits and penetration testing focusing on web application input handling. 7. Limit privileges of users who can modify JetElements content to reduce the risk of malicious content injection. 8. Monitor logs and user activity for unusual behavior indicative of attempted exploitation. 9. Consider temporarily disabling vulnerable JetElements widgets if feasible until patches are released.
