CVE-2025-60234 is a vulnerability classified as deserialization of untrusted data in the designthemes Single Property plugin, versions up to 2.8. This vulnerability allows an attacker to perform object injection by sending crafted serialized data to the application, which the plugin improperly deserializes without sufficient validation or sanitization. Object injection can lead to remote code execution, privilege escalation, or arbitrary code execution depending on the application context. The CVSS v3.1 score of 8.8 reflects a high severity, with attack vector being network-based (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The impact affects confidentiality, integrity, and availability at a high level, indicating potential full system compromise. Although no public exploits are currently known, the vulnerability's nature and ease of exploitation make it a critical risk. The plugin is commonly used in WordPress environments for real estate listings, making it a target for attackers seeking to compromise websites and underlying infrastructure. The vulnerability was reserved on 2025-09-25 and published on 2025-10-22, indicating recent disclosure and likely pending patches or mitigations.

For European organizations, the impact of CVE-2025-60234 can be severe. Organizations using the Single Property plugin for real estate or property management websites may face unauthorized access to sensitive customer data, including personal and financial information. Attackers exploiting this vulnerability could execute arbitrary code on web servers, leading to website defacement, data theft, or pivoting to internal networks. This can disrupt business operations, damage reputation, and result in regulatory penalties under GDPR due to data breaches. The high severity and network exploitability increase the likelihood of targeted attacks, especially against organizations with limited security controls. Additionally, availability impacts could cause downtime, affecting customer trust and revenue. The vulnerability's presence in a widely used WordPress plugin amplifies the risk across multiple sectors in Europe, including real estate, hospitality, and property management services.

1. Immediate application of vendor patches once released is critical; monitor designthemes official channels for updates. 2. Until patches are available, restrict access to the Single Property plugin functionality by implementing IP whitelisting or VPN access for administrative interfaces. 3. Deploy Web Application Firewalls (WAFs) with rules specifically targeting deserialization attacks and object injection patterns to detect and block malicious payloads. 4. Conduct code audits and disable or remove unused plugin features that handle serialized data. 5. Implement strict input validation and sanitization on all data inputs processed by the plugin. 6. Monitor logs for unusual deserialization activity or errors indicative of exploitation attempts. 7. Educate IT and security teams about this vulnerability to ensure rapid detection and response. 8. Consider isolating WordPress environments hosting the plugin to limit lateral movement in case of compromise. 9. Regularly back up website data and configurations to enable quick recovery if exploitation occurs.
