CVE-2025-67565 is a vulnerability identified in the sizam Rehub WordPress theme, specifically affecting versions up to and including 19.9.9.1. The issue involves the unintended exposure of sensitive system information to unauthorized control spheres, meaning that attackers can retrieve embedded sensitive data without proper authorization. This vulnerability arises from inadequate access controls or improper sanitization within the theme's code, allowing attackers to access information that should be restricted. The exposed data could include configuration details, system paths, or other embedded sensitive information that could aid further attacks or reconnaissance. No authentication or user interaction is required to exploit this vulnerability, increasing its risk profile. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and published in the CVE database, indicating that threat actors could develop exploits. The absence of a CVSS score means that severity must be inferred from the nature of the vulnerability, which impacts confidentiality primarily, with potential indirect effects on integrity and availability if attackers leverage the information for further attacks. The vulnerability affects a widely used WordPress theme, which is popular among e-commerce and affiliate marketing websites, increasing the potential attack surface.

For European organizations, the exposure of sensitive system information can lead to significant risks including data breaches, targeted attacks, and loss of customer trust. Attackers gaining access to configuration or system details can craft more effective exploits, potentially leading to privilege escalation, data theft, or service disruption. Organizations relying on the Rehub theme for e-commerce or content delivery may face operational and reputational damage. The impact is heightened in sectors handling personal data under GDPR, where unauthorized data exposure can result in regulatory penalties. Additionally, the vulnerability could be leveraged in multi-stage attacks against critical infrastructure or business-critical applications hosted on WordPress platforms. The ease of exploitation without authentication means that attackers can scan and target vulnerable sites en masse, increasing the likelihood of widespread impact across European digital ecosystems.

Immediate mitigation involves monitoring for and applying official patches or updates from the sizam vendor once available. Until a patch is released, organizations should conduct manual code audits of the Rehub theme to identify and restrict access to sensitive data exposure points. Implementing web application firewalls (WAFs) with custom rules to block suspicious requests targeting the vulnerable endpoints can reduce risk. Restricting file and directory permissions on the server to limit unauthorized data retrieval is advisable. Organizations should also review and harden WordPress security configurations, including disabling unnecessary theme features that expose system information. Regular security scanning and penetration testing focused on the Rehub theme can help detect exploitation attempts. Finally, maintaining comprehensive logging and alerting mechanisms will aid in early detection of suspicious activities related to this vulnerability.
