CVE-2025-53985 is a vulnerability classified under CWE-201, which involves the insertion of sensitive information into sent data within the Crocoblock JetTabs plugin. JetTabs is a WordPress plugin used to create tabbed content on websites. This vulnerability affects versions up to 2.2.9. The issue allows an attacker with at least low-level privileges (PR:L) to retrieve embedded sensitive data that is unintentionally included in data sent by the plugin. The vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope is unchanged (S:U). The confidentiality impact is high (C:H), meaning sensitive data exposure is significant, but there is no impact on integrity (I:N) or availability (A:N). Exploitation requires some level of privilege on the target system, but no user interaction is needed. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability likely arises from the plugin embedding sensitive information such as credentials, tokens, or private data into data sent over the network, which can be intercepted or accessed by unauthorized parties with some access to the system or network. This could lead to data leakage and potential further compromise if sensitive information is exposed.

For European organizations using Crocoblock JetTabs on their WordPress sites, this vulnerability poses a risk of sensitive data leakage. Given the high confidentiality impact, exposure of embedded sensitive information could lead to unauthorized access to internal systems, user data, or administrative credentials. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations), and potential financial losses. Since the vulnerability requires some privilege level, attackers might exploit it after gaining limited access, escalating their capabilities. Organizations with customer-facing websites or portals using JetTabs could inadvertently expose sensitive customer or business data. The lack of impact on integrity and availability means the threat is primarily data confidentiality compromise rather than service disruption or data manipulation. However, the exposure of sensitive data can be a stepping stone for more severe attacks. The absence of known exploits in the wild suggests a window for proactive mitigation before widespread exploitation. European entities in sectors with strict data protection requirements, such as finance, healthcare, and government, should be particularly vigilant.

1. Immediate assessment of all WordPress sites using Crocoblock JetTabs should be conducted to identify affected versions (up to 2.2.9). 2. Until an official patch is released, restrict access to the WordPress admin panel and any interfaces that could allow privilege escalation or data access, using strong authentication and IP whitelisting where possible. 3. Monitor network traffic for unusual data transmissions that may include sensitive information leakage. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting JetTabs endpoints. 5. Review and minimize the sensitive data stored or processed by the plugin to reduce exposure risk. 6. Engage with Crocoblock support or security advisories to obtain patches or updates as soon as they become available and apply them promptly. 7. Conduct internal audits and penetration testing focusing on privilege escalation and data leakage vectors related to JetTabs. 8. Educate site administrators on the risks and ensure they follow the principle of least privilege for user roles. 9. Consider temporary disabling or replacing JetTabs with alternative plugins if mitigation is not feasible in the short term.
