CVE-2025-55714 is a medium-severity vulnerability classified as CWE-79, which corresponds to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the Crocoblock JetElements plugin for Elementor, a popular WordPress page builder. Specifically, the flaw allows for Stored XSS attacks, where malicious scripts injected by an attacker are permanently stored on the target server (e.g., in a database) and later executed in the browsers of users who visit the affected web pages. The vulnerability exists in versions of JetElements for Elementor up to and including 2.7.9. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be performed remotely over the network with low attack complexity, requires low privileges (authenticated user), and requires user interaction (victim must visit the malicious page). The scope is changed, meaning the vulnerability affects resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent. Stored XSS can lead to session hijacking, defacement, redirection to malicious sites, or execution of arbitrary scripts in the context of the affected website, potentially compromising user data and trust. No known exploits are currently reported in the wild, and no patches are linked yet, indicating that mitigation may require vendor updates or manual intervention. Since JetElements is a widely used plugin for Elementor, which itself is a dominant WordPress page builder, the vulnerability could affect numerous websites that use this plugin, especially those that allow authenticated users to submit content that is not properly sanitized. The vulnerability arises from improper input validation and output encoding during web page generation, allowing malicious payloads to be stored and executed in other users' browsers.

For European organizations, this vulnerability poses a significant risk particularly to those relying on WordPress websites enhanced with JetElements for Elementor. Stored XSS can lead to theft of sensitive user information such as authentication cookies, enabling attackers to impersonate users or administrators. This can result in unauthorized access to internal systems or customer data, violating GDPR requirements for data protection and potentially leading to regulatory fines. Additionally, exploitation could damage brand reputation and customer trust if websites are defaced or used to distribute malware. Organizations in sectors such as e-commerce, finance, healthcare, and government, which often use WordPress for public-facing sites, are especially vulnerable. The requirement for low privileges means that even users with minimal access could exploit this flaw, increasing the attack surface. The need for user interaction (visiting a malicious page) means social engineering or phishing could be used to trigger the exploit. The changed scope indicates that the impact could extend beyond the immediate plugin, potentially affecting other integrated components or services. Given the widespread use of Elementor and its plugins in Europe, the threat is relevant and should be addressed promptly.

1. Immediate mitigation should include restricting user input fields that allow content submission to trusted users only and implementing strict content moderation policies. 2. Employ Web Application Firewalls (WAFs) with rules designed to detect and block common XSS payloads targeting JetElements. 3. Disable or remove the JetElements plugin temporarily if feasible until a vendor patch is released. 4. For developers and site administrators, implement additional input validation and output encoding on all user-supplied data, especially in areas handled by JetElements. 5. Monitor website logs for unusual activity or attempts to inject scripts. 6. Educate users and administrators about phishing risks to reduce the chance of social engineering exploitation. 7. Once a patch is available from Crocoblock, apply it promptly and verify the fix. 8. Conduct regular security audits and penetration testing focusing on XSS vulnerabilities in WordPress plugins. 9. Consider Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. These measures go beyond generic advice by focusing on the specific plugin, user roles, and operational controls relevant to the threat.
