CVE-2025-14358 identifies a critical security vulnerability in the sizam REHub Framework, a popular WordPress theme and plugin suite used for building multi-vendor marketplaces, affiliate marketing sites, and price comparison platforms. The vulnerability stems from missing authorization checks, meaning certain functions within the framework are accessible without proper verification of user privileges. Specifically, access control lists (ACLs) that should restrict sensitive operations are either absent or improperly enforced, allowing unauthenticated attackers to invoke these functions remotely. The CVSS 3.1 base score of 9.8 reflects the vulnerability's high impact and ease of exploitation: it requires no privileges, no user interaction, and can be exploited over the network. Successful exploitation could lead to full compromise of the affected system’s confidentiality, integrity, and availability, including unauthorized data access, modification, or deletion, and potential disruption of services. Although no public exploits have been reported yet, the vulnerability’s critical nature demands urgent attention. The affected versions include all releases up to and including 19.9.5, with no patch currently available at the time of reporting. The vulnerability was reserved in December 2025 and published in January 2026, indicating recent discovery. The REHub Framework’s widespread use in European e-commerce and affiliate marketing sites increases the risk profile for organizations relying on this software.

For European organizations, the impact of CVE-2025-14358 could be severe. The REHub Framework is widely used in online marketplaces and affiliate marketing platforms, which often handle sensitive customer data, transaction records, and business-critical operations. Exploitation could lead to unauthorized disclosure of personal and financial data, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. Integrity breaches could allow attackers to manipulate product listings, pricing, or affiliate commissions, causing financial losses and undermining trust. Availability impacts could disrupt e-commerce operations, leading to lost revenue and customer dissatisfaction. Given the framework’s role in multi-vendor environments, a single exploited site could cascade effects across multiple stakeholders. The lack of authentication and user interaction requirements makes this vulnerability particularly dangerous, as attackers can automate exploitation at scale. European organizations with limited cybersecurity resources or delayed patch management processes are especially vulnerable to rapid compromise.

Immediate mitigation steps include monitoring network traffic for unusual access patterns targeting REHub Framework endpoints and implementing web application firewalls (WAFs) with custom rules to block unauthorized requests to sensitive functions. Organizations should isolate affected systems from public access where feasible until patches are released. Employing strict network segmentation and limiting inbound traffic to trusted sources can reduce exposure. Administrators should audit user roles and permissions within WordPress to minimize potential damage. Once available, applying official patches or updates from sizam is critical. In the absence of patches, consider temporary code-level access control enhancements or disabling vulnerable features. Regular backups and incident response readiness will help mitigate damage if exploitation occurs. Additionally, organizations should engage in threat intelligence sharing to stay informed about emerging exploits targeting this vulnerability.
