CVE-2025-64199 is a missing authorization vulnerability identified in the WpEstate wpresidence WordPress plugin, affecting versions up to and including 5.3.2. This vulnerability arises from improperly configured access control mechanisms that fail to enforce authorization checks on certain plugin functionalities. As a result, remote attackers can access restricted resources or information without authentication or user interaction. The CVSS v3.1 base score is 5.3, indicating a medium severity level, with an attack vector classified as network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impact limited to confidentiality (C:L) without affecting integrity or availability. The vulnerability does not require any prior authentication, making exploitation feasible remotely over the internet. However, the impact is limited to information disclosure rather than modification or denial of service. No known exploits have been reported in the wild, and no official patches have been linked yet, though the vulnerability was published on October 29, 2025. The vulnerability primarily affects websites using the wpresidence plugin for real estate listings, which is popular among WordPress-based real estate platforms. The missing authorization flaw could allow attackers to gather sensitive information about listings or user data that should otherwise be protected by access controls.

For European organizations, especially those operating real estate websites using the wpresidence plugin, this vulnerability poses a risk of unauthorized information disclosure. While the impact does not extend to data integrity or availability, exposure of confidential data could lead to privacy violations, reputational damage, and potential regulatory non-compliance under GDPR. Attackers could harvest sensitive listing details or user information, which might be leveraged for further targeted attacks or social engineering. Organizations relying on wpresidence for client-facing portals or internal management should be aware that attackers do not need credentials or user interaction to exploit this flaw, increasing the risk surface. The medium severity rating reflects the limited scope of impact but acknowledges the ease of exploitation and the broad network attack vector. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as threat actors often develop exploits following public disclosure.

European organizations should immediately audit their use of the wpresidence plugin to determine if affected versions (up to 5.3.2) are in use. Until an official patch is released, implement compensating controls such as restricting access to wpresidence administrative and sensitive endpoints via IP whitelisting or VPN access. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting wpresidence functionalities. Monitor server and application logs for unusual access patterns or repeated unauthorized attempts. Regularly back up website data and configurations to enable recovery if exploitation occurs. Engage with the plugin vendor or community to track patch releases and apply updates promptly once available. Additionally, consider isolating the WordPress environment or deploying security plugins that enforce stricter access control policies. Conduct security awareness training for administrators to recognize potential exploitation indicators and maintain vigilance over plugin security advisories.
