CVE-2025-53196 is a vulnerability identified in the Crocoblock JetEngine plugin, a popular tool used primarily in WordPress environments to create dynamic content and custom post types. The vulnerability is classified under CWE-201, which involves the insertion of sensitive information into sent data, leading to the unauthorized retrieval of embedded sensitive data. Specifically, this flaw allows an attacker with at least low-level privileges (PR:L) to remotely access sensitive information transmitted by the JetEngine plugin without requiring user interaction (UI:N). The vulnerability affects versions up to and including 3.7.0, though the exact starting affected version is unspecified (noted as n/a). The CVSS v3.1 base score is 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), and the scope remains unchanged (S:U). The impact is primarily on confidentiality (C:H), with no impact on integrity or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. This vulnerability could lead to leakage of sensitive data embedded within the plugin's data transmissions, potentially exposing user or system information that should remain confidential. Given JetEngine's role in managing dynamic content and custom fields, sensitive data could include user metadata, configuration details, or other private information embedded in requests or responses handled by the plugin.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites enhanced by Crocoblock JetEngine for business-critical applications, e-commerce, or customer data management. The unauthorized disclosure of sensitive information could lead to privacy violations under GDPR, resulting in regulatory fines and reputational damage. Confidential data leakage could also aid attackers in further exploitation, such as targeted phishing or lateral movement within networks. Organizations in sectors like finance, healthcare, and government, which often handle sensitive personal or operational data, are particularly at risk. Additionally, since the vulnerability requires low privileges but no user interaction, insider threats or compromised accounts could be leveraged to exploit this flaw remotely, increasing the attack surface. The absence of a patch at this time means organizations must rely on mitigation strategies to reduce exposure. The medium severity rating suggests that while the vulnerability is serious, it does not directly allow system compromise or denial of service, but the confidentiality breach alone is critical in regulated environments.

1. Immediate mitigation should include restricting access to the WordPress admin and JetEngine management interfaces to trusted users only, enforcing strong authentication and role-based access controls to minimize the risk of low-privilege accounts being exploited. 2. Monitor network traffic for unusual data transmissions from JetEngine endpoints that could indicate exploitation attempts. 3. Disable or limit the use of JetEngine features that handle sensitive data until a patch is released. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting JetEngine plugin endpoints. 5. Regularly audit and review user privileges within WordPress to ensure no unnecessary elevated access is granted. 6. Stay updated with Crocoblock vendor announcements for official patches or updates addressing this vulnerability and apply them promptly once available. 7. Consider isolating or segmenting WordPress environments hosting JetEngine to limit lateral movement in case of compromise. 8. Conduct security awareness training for administrators and users about the risks of privilege misuse and data leakage.
