CVE-2025-9112 is a high-severity vulnerability affecting the Doccure WordPress theme developed by dreamstechnologies, specifically in all versions up to and including 1.4.8. The vulnerability arises from improper validation of file types in the 'doccure_temp_file_uploader' function, which allows authenticated users with subscriber-level or higher permissions to upload arbitrary files to the web server hosting the affected WordPress site. This weakness is classified under CWE-434, which pertains to unrestricted file upload vulnerabilities. Because the validation mechanism fails to restrict dangerous file types, attackers can upload malicious files such as web shells or scripts that can be executed remotely, potentially leading to remote code execution (RCE). The CVSS v3.1 base score is 8.8, indicating a high severity with network attack vector, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability presents a significant risk due to the ease of exploitation by authenticated users and the critical impact of a successful attack. The vulnerability affects all versions of the Doccure theme prior to the fix, and since WordPress themes are widely used, any site using this theme without patching is vulnerable. The lack of official patches or mitigation links at the time of publication increases the urgency for administrators to take protective measures.

For European organizations, the impact of this vulnerability can be severe, especially for those relying on WordPress sites with the Doccure theme for healthcare or appointment booking services, as Doccure is often used in medical and clinic-related websites. Successful exploitation could lead to unauthorized access to sensitive patient data, disruption of services, defacement of websites, or use of compromised servers as pivot points for further attacks within the organization’s network. The breach of confidentiality and integrity of data could also lead to violations of GDPR regulations, resulting in legal and financial penalties. Additionally, availability impacts could disrupt critical online services, damaging organizational reputation and trust. Given the high CVSS score and the potential for remote code execution, attackers could gain full control over the web server, enabling persistent access and lateral movement. The threat is particularly concerning for organizations with limited cybersecurity resources or those that do not regularly update their WordPress themes and plugins.

1. Immediate action should be to update the Doccure theme to a patched version once available from the vendor. Until a patch is released, consider temporarily disabling or restricting access to the file upload functionality within the theme. 2. Implement strict access controls to limit subscriber-level permissions and review user roles to ensure only trusted users have upload capabilities. 3. Employ web application firewalls (WAF) with custom rules to detect and block suspicious file upload attempts, especially those containing executable code or uncommon file extensions. 4. Use server-side file type validation and scanning tools to verify uploaded files against allowed MIME types and scan for malware signatures. 5. Monitor web server logs and WordPress activity logs for unusual upload activity or execution of unexpected scripts. 6. Harden the server environment by disabling execution permissions in upload directories to prevent execution of uploaded malicious files. 7. Regularly back up website data and configurations to enable quick recovery in case of compromise. 8. Educate site administrators and users about the risks of file uploads and the importance of applying security updates promptly.
