CVE-2025-67535 is a vulnerability classified as deserialization of untrusted data in the WP Maps plugin by WePlugins, a WordPress development company. This vulnerability arises when the plugin improperly handles serialized data inputs, allowing an attacker to inject malicious objects during the deserialization process. Object injection can lead to remote code execution, privilege escalation, or other impacts depending on the context and the objects injected. The affected versions include all WP Maps releases up to 4.8.6. The CVSS v3.1 score is 6.5, with vector AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H, indicating that exploitation requires local access with high privileges and user interaction, but can result in high impact on confidentiality, integrity, and availability. No public patches or known exploits are currently available, but the vulnerability is published and should be addressed promptly. The plugin is commonly used in WordPress sites to display Google Maps, making it a target for attackers seeking to compromise websites or escalate privileges within hosting environments.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites with the WP Maps plugin installed. Successful exploitation could lead to unauthorized access to sensitive data, defacement or manipulation of website content, and disruption of services. This could damage reputation, lead to data breaches under GDPR regulations, and cause operational downtime. Organizations in sectors such as e-commerce, government, education, and media that use WordPress extensively are particularly at risk. The requirement for local high-privilege access and user interaction reduces the likelihood of widespread remote exploitation but does not eliminate risk from insider threats or compromised user accounts.

1. Immediately audit WordPress installations to identify the presence and version of the WP Maps plugin. 2. Disable or remove the WP Maps plugin if it is not essential to reduce attack surface. 3. Monitor for plugin updates from WePlugins and apply patches as soon as they are released. 4. Restrict administrative and high-privilege user access to trusted personnel only, enforcing strong authentication and session management. 5. Implement application-level monitoring to detect unusual deserialization activities or unexpected object injections. 6. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting deserialization endpoints. 7. Conduct regular security training to reduce the risk of social engineering that could facilitate user interaction required for exploitation. 8. Review and harden server and WordPress configurations to limit the impact of potential exploitation.
