CVE-2025-67565 is a vulnerability identified in the sizam Rehub WordPress theme, affecting all versions up to and including 19.9.9.1. The flaw allows unauthorized remote attackers to retrieve embedded sensitive system information without requiring authentication or user interaction. The vulnerability is classified as an information disclosure issue, where sensitive data embedded within the theme files or configuration can be accessed by an attacker simply by sending crafted requests over the network. The CVSS 3.1 base score is 5.3 (medium), reflecting the ease of exploitation (network vector, low attack complexity, no privileges or user interaction required) but limited impact confined to confidentiality only, with no effect on integrity or availability. The exposed information could include system paths, configuration details, or other sensitive metadata that could facilitate further targeted attacks such as privilege escalation or lateral movement. No known exploits are currently reported in the wild, but the vulnerability's public disclosure means attackers may develop exploits. The issue affects WordPress sites using the Rehub theme, which is popular among affiliate marketers and e-commerce platforms, making it a relevant concern for online businesses relying on this theme for their web presence.

For European organizations, the exposure of sensitive system information can increase the risk of targeted attacks by providing attackers with reconnaissance data that can be leveraged to identify other vulnerabilities or misconfigurations. While the vulnerability does not directly compromise data integrity or availability, the confidentiality breach can lead to subsequent exploitation steps, such as credential theft or privilege escalation. Organizations in sectors with high online presence, such as retail, affiliate marketing, and digital services, are particularly at risk. The impact is heightened in regulated environments where data protection compliance (e.g., GDPR) mandates safeguarding all sensitive information, and any leakage could result in legal and reputational consequences. Additionally, attackers could use the disclosed information to craft more effective phishing or social engineering campaigns targeting European users or employees.

1. Monitor for and apply official patches or updates from the sizam Rehub theme vendor as soon as they become available to remediate the vulnerability. 2. In the interim, restrict access to theme files and directories via web server configuration (e.g., .htaccess rules) to prevent unauthorized retrieval of sensitive files. 3. Conduct a thorough audit of the exposed data to understand what sensitive information is at risk and remove or obfuscate any unnecessary embedded data within theme files. 4. Implement Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting theme files. 5. Limit administrative and file system access to trusted personnel only and enforce strong authentication mechanisms. 6. Regularly scan the website for information disclosure vulnerabilities using automated tools and penetration testing. 7. Educate website administrators about the risks of using outdated themes and the importance of timely updates.
