CVE-2025-69035 is a vulnerability classified as deserialization of untrusted data in the Dental Care CPT plugin developed by strongholdthemes, affecting versions up to and including 20.2. Deserialization vulnerabilities occur when untrusted input is deserialized into objects without proper validation, enabling attackers to inject malicious objects. This can lead to object injection attacks, allowing attackers to execute arbitrary code, escalate privileges, or manipulate application logic. The vulnerability requires low privileges (PR:L) but no user interaction (UI:N) and can be exploited remotely over the network (AV:N). The CVSS v3.1 score of 8.8 reflects high impact on confidentiality, integrity, and availability, indicating potential full system compromise. The plugin is typically used in WordPress environments to manage dental care CPT (Current Procedural Terminology) codes, which are critical for healthcare billing and management. The absence of available patches at the time of publication increases the urgency for mitigation. No known exploits have been reported in the wild yet, but the nature of the vulnerability and its ease of exploitation make it a prime target for attackers. The vulnerability was reserved late December 2025 and published in January 2026, indicating recent discovery and disclosure.

For European organizations, particularly those in the healthcare sector using WordPress and the Dental Care CPT plugin, this vulnerability poses a severe risk. Exploitation could lead to unauthorized access to sensitive patient data, manipulation of billing codes, disruption of healthcare services, and potential ransomware deployment. The compromise of confidentiality violates GDPR requirements, exposing organizations to legal and financial penalties. Integrity breaches could result in fraudulent billing or incorrect patient records, impacting patient care and trust. Availability impacts could disrupt critical healthcare operations. Given the healthcare sector's strategic importance and the sensitivity of medical data, successful exploitation could have cascading effects on patient safety and organizational reputation. The remote exploitability and lack of required user interaction increase the likelihood of automated attacks targeting vulnerable installations across Europe.

Immediate mitigation steps include auditing all WordPress installations for the presence of the Dental Care CPT plugin and verifying the version. Until an official patch is released, organizations should consider disabling or removing the plugin if not essential. Restrict access to the WordPress admin interface and plugin files using IP whitelisting or VPNs to reduce exposure. Implement Web Application Firewalls (WAFs) with rules to detect and block suspicious deserialization payloads or unusual plugin activity. Monitor logs for anomalous behavior indicative of exploitation attempts, such as unexpected object deserialization or privilege escalations. Regularly back up critical data and test restoration procedures to mitigate potential data loss. Engage with the vendor or security community for updates on patches or workarounds. Educate IT and security teams about the risks of deserialization vulnerabilities and ensure secure coding practices in custom plugins or themes to prevent similar issues.
