CVE-2025-53982 is a stored Cross-site Scripting (XSS) vulnerability identified in the Crocoblock JetElements plugin for Elementor, a popular WordPress page builder. The vulnerability arises due to improper neutralization of input during web page generation (CWE-79), allowing malicious actors to inject and store arbitrary scripts within the plugin's content. When other users or administrators view the affected pages, the malicious script executes in their browsers. This can lead to session hijacking, defacement, redirection to malicious sites, or other client-side attacks. The vulnerability affects JetElements versions up to and including 2.7.7. The CVSS v3.1 base score is 6.5 (medium severity), reflecting that the attack vector is network-based (AV:N), requires low privileges (PR:L), and user interaction (UI:R), but can impact confidentiality, integrity, and availability (scope changed). No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. Stored XSS is particularly dangerous because the malicious payload persists on the server and can affect multiple users over time. Given JetElements' role in rendering dynamic content on WordPress sites, this vulnerability could be exploited to compromise site visitors or administrators, potentially leading to broader compromise of the affected websites.

For European organizations using WordPress sites with the JetElements plugin, this vulnerability poses a significant risk to both website integrity and user trust. Exploitation could lead to unauthorized access to user sessions, theft of sensitive data, or distribution of malware to site visitors. This is especially critical for e-commerce, governmental, or financial websites where user data confidentiality and site availability are paramount. The scope of impact includes potential defacement or disruption of services, damaging organizational reputation and possibly violating GDPR requirements related to data protection and breach notification. Since the vulnerability requires some level of user interaction and low privileges, insider threats or compromised user accounts could be leveraged to exploit this flaw. The persistence of the malicious script increases the risk of widespread impact over time if not remediated promptly.

European organizations should immediately audit their WordPress installations for the presence of the JetElements plugin and verify the version in use. Until an official patch is released, it is advisable to disable or remove the JetElements plugin to eliminate the attack surface. Implement strict input validation and output encoding on all user-generated content fields within the plugin's scope, if customization is possible. Employ Web Application Firewalls (WAFs) with rules targeting common XSS payloads to provide a temporary protective layer. Regularly monitor website logs and user activity for signs of suspicious behavior or injected scripts. Educate site administrators and content editors about the risks of stored XSS and the importance of cautious content management. Finally, maintain up-to-date backups to enable rapid recovery in case of compromise.
