CVE-2025-64199 is a missing authorization vulnerability identified in the WpEstate wpresidence WordPress plugin, affecting versions up to and including 5.3.2. The flaw arises from incorrectly configured access control mechanisms within the plugin, which allow unauthenticated attackers to bypass authorization checks. This can lead to unauthorized access to certain data or functionality that should be restricted. The vulnerability is exploitable remotely over the network without requiring any privileges or user interaction, increasing its exposure. However, the impact is limited to confidentiality as there is no indication of integrity or availability compromise. The CVSS v3.1 score of 5.3 reflects these characteristics: attack vector is network (AV:N), attack complexity is low (AC:L), no privileges required (PR:N), no user interaction (UI:N), and the impact is limited to confidentiality (C:L) with no integrity (I:N) or availability (A:N) impact. No known exploits have been reported in the wild, and no official patches have been linked yet, though the vulnerability has been publicly disclosed. The issue primarily affects websites using the wpresidence plugin for real estate listings, which may expose sensitive listing or user data if exploited. The vulnerability underscores the importance of proper access control implementation in WordPress plugins, especially those handling sensitive or business-critical data.

For European organizations, particularly those operating real estate websites using the wpresidence plugin, this vulnerability poses a risk of unauthorized data disclosure. Sensitive information such as property listings, user contact details, or internal configuration data could be exposed, potentially leading to privacy violations or competitive disadvantages. While the vulnerability does not allow data modification or service disruption, the confidentiality breach could damage organizational reputation and customer trust. Given the widespread use of WordPress in Europe and the popularity of real estate platforms, the attack surface is significant. Organizations in sectors like real estate agencies, property management, and related services are most at risk. The lack of known exploits reduces immediate threat levels but does not eliminate the risk, especially as attackers may develop exploits following public disclosure. Compliance with European data protection regulations such as GDPR also raises the stakes for protecting personal data from unauthorized access.

1. Monitor official WpEstate channels and security advisories for patches addressing CVE-2025-64199 and apply them promptly once available. 2. Until patches are released, implement web application firewall (WAF) rules to restrict access to wpresidence plugin endpoints, limiting exposure to unauthenticated requests. 3. Conduct a thorough audit of access control configurations within the wpresidence plugin and the broader WordPress environment to identify and remediate any misconfigurations. 4. Restrict administrative and sensitive plugin functionality to authenticated and authorized users only, using WordPress role management and capability settings. 5. Employ network segmentation and IP whitelisting where feasible to limit access to backend management interfaces. 6. Regularly review server and application logs for unusual access patterns indicative of exploitation attempts. 7. Educate site administrators on the importance of timely plugin updates and secure configuration practices. 8. Consider deploying intrusion detection systems (IDS) tuned to detect anomalous access to wpresidence resources. These measures collectively reduce the risk of exploitation and limit potential data exposure.
