CVE-2025-0371 is a stored cross-site scripting vulnerability identified in the Crocoblock JetElements plugin for WordPress, affecting all versions up to and including 2.7.2.1. The root cause is improper neutralization of user-supplied input during web page generation, specifically insufficient input sanitization and output escaping in several JetElements widgets. This flaw allows authenticated attackers with contributor-level privileges or higher to inject arbitrary JavaScript code into pages. Because the malicious scripts are stored persistently, they execute every time a user accesses the infected page, potentially compromising user sessions, stealing cookies, or performing actions on behalf of the victim. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting medium severity, with an attack vector of network, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality and integrity with a scope change. No public exploits have been reported yet, but the vulnerability poses a significant risk given the widespread use of WordPress and JetElements. The vulnerability was published on January 21, 2025, and assigned by Wordfence. No official patches or updates are linked yet, so users must apply interim mitigations. This vulnerability highlights the importance of proper input validation and output encoding in web applications, especially plugins that extend CMS functionality.

The impact of CVE-2025-0371 is primarily on the confidentiality and integrity of affected WordPress sites and their users. Successful exploitation allows an attacker with contributor-level access to inject persistent malicious scripts that execute in the context of any user viewing the compromised page. This can lead to session hijacking, theft of sensitive user data such as cookies or credentials, unauthorized actions performed on behalf of users, defacement of websites, and potential pivoting to further attacks within the network. Since contributor-level access is relatively low privilege, attackers who gain such access through compromised accounts or social engineering can leverage this vulnerability to escalate their impact. The scope includes all websites using vulnerable JetElements versions, which may be numerous given WordPress’s market share. Although no known exploits are currently in the wild, the medium CVSS score and ease of exploitation by authenticated users make this a credible threat that could be weaponized in targeted attacks or automated campaigns. Organizations relying on JetElements for site functionality risk reputational damage, data breaches, and user trust erosion if exploited.

To mitigate CVE-2025-0371, organizations should first check for and apply any official patches or updates from Crocoblock as they become available. In the absence of patches, immediate steps include restricting contributor-level access to trusted users only, as this vulnerability requires authenticated contributor privileges. Implement strict input validation and output encoding on all user-supplied data within JetElements widgets, potentially via custom code or security plugins that sanitize inputs before storage and escape outputs before rendering. Employ Web Application Firewalls (WAFs) with rules targeting common XSS payloads to block exploitation attempts. Monitor logs and user activity for unusual behavior indicative of exploitation, such as unexpected script injections or anomalous contributor actions. Educate site administrators and content contributors about the risks of XSS and the importance of secure content handling. Consider temporarily disabling vulnerable widgets if feasible until a patch is released. Regularly audit WordPress plugins for vulnerabilities and maintain a principle of least privilege for user roles to minimize attack surface.
