CVE-2025-67926 is a missing authorization vulnerability found in the Shahjahan Jewel Fluent Support plugin, a tool commonly used for customer support ticketing and service management within WordPress environments. The vulnerability exists due to incorrectly configured access control security levels, allowing an attacker with low privileges (PR:L) to perform unauthorized actions without requiring user interaction (UI:N). The vulnerability affects all versions up to and including 1.10.4. The CVSS 3.1 base score of 8.8 reflects the critical nature of this flaw, with network attack vector (AV:N), low attack complexity (AC:L), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker can remotely exploit the vulnerability to gain unauthorized access to sensitive data, modify or delete data, and disrupt service availability. Although no known exploits are currently reported in the wild, the vulnerability’s characteristics make it a prime target for attackers once exploit code becomes available. The lack of proper authorization checks indicates that the plugin fails to verify whether a user has sufficient permissions before allowing access to sensitive functions or data, which could lead to privilege escalation or data leakage. The vulnerability was reserved in December 2025 and published in January 2026, indicating recent discovery and disclosure. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate attention from users of this plugin.

For European organizations, especially those relying on WordPress-based customer support systems using Fluent Support, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer data, including personally identifiable information (PII), violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. The ability to alter or delete support tickets and related data can disrupt business operations and degrade customer trust. Availability impact could result in denial of service for support functions, affecting service quality and compliance with service-level agreements. Industries such as e-commerce, financial services, and telecommunications, which heavily depend on customer support platforms, are particularly vulnerable. The network-based attack vector means that attackers can exploit this vulnerability remotely, increasing the threat surface. Given the high severity and potential for full system compromise, European organizations must prioritize remediation to avoid operational, financial, and legal consequences.

1. Monitor Shahjahan Jewel’s official channels for patches addressing CVE-2025-67926 and apply updates immediately upon release. 2. In the interim, restrict network access to the Fluent Support plugin interfaces by implementing firewall rules or IP whitelisting to limit exposure to trusted users only. 3. Conduct a thorough audit of user roles and permissions within WordPress to ensure that only necessary users have access to support plugin functionalities. 4. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 5. Implement strict logging and monitoring of access to the Fluent Support plugin to detect anomalous activities indicative of exploitation attempts. 6. Consider isolating the support system from other critical infrastructure to contain potential breaches. 7. Educate administrators and support staff about the vulnerability and the importance of minimizing privilege assignments. 8. If feasible, temporarily disable or deactivate the Fluent Support plugin until a patch is available, especially if it is not critical to immediate operations.
