CVE-2025-64199 identifies a missing authorization vulnerability in the WpEstate wpresidence WordPress plugin, affecting versions up to and including 5.3.2. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user is authorized to perform certain actions within the plugin. This misconfiguration can allow attackers to bypass authorization checks, potentially enabling unauthorized users to access or manipulate sensitive data or functionality within the wpresidence plugin environment. The plugin is widely used for managing real estate listings and property-related content on WordPress sites. Although no public exploits have been reported, the flaw represents a significant security risk because it undermines the fundamental security principle of access control. The vulnerability was published on October 29, 2025, but no CVSS score has been assigned yet, and no patches or mitigations have been officially released at the time of this report. The lack of authentication requirements for exploitation and the broad scope of affected versions increase the risk profile. Organizations using wpresidence should be aware that attackers could leverage this vulnerability to gain unauthorized access to administrative or sensitive functions, potentially leading to data leakage, unauthorized content modification, or further compromise of the hosting environment.

For European organizations, the impact of CVE-2025-64199 can be substantial, particularly for those operating real estate websites or platforms using the wpresidence plugin. Unauthorized access could lead to exposure of confidential client information, property details, or internal business data, damaging reputation and violating data protection regulations such as GDPR. Integrity of listings and transactional data could be compromised, leading to misinformation or fraudulent activities. Availability impact is less direct but could occur if attackers manipulate plugin functionality to disrupt service. The risk is amplified in sectors where trust and data accuracy are critical, such as real estate agencies, property management firms, and related service providers. Additionally, unauthorized access could serve as a foothold for further attacks on the hosting infrastructure. European organizations may face regulatory penalties if personal data is exposed due to inadequate access controls. The absence of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks once the vulnerability becomes widely known.

To mitigate CVE-2025-64199, European organizations should implement the following specific measures: 1) Immediately audit all WordPress installations for the presence of the wpresidence plugin and identify affected versions (<= 5.3.2). 2) Monitor official WpEstate channels and security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 3) In the interim, restrict plugin access to trusted users only by enforcing strict role-based access controls within WordPress, minimizing the number of users with administrative or elevated privileges. 4) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting wpresidence endpoints. 5) Conduct thorough access control reviews and penetration testing focused on the wpresidence plugin to identify and remediate any additional misconfigurations. 6) Regularly back up website data and configurations to enable rapid recovery in case of compromise. 7) Educate site administrators about the risks of unauthorized access and encourage vigilance for unusual activity related to the plugin. 8) Consider isolating the wpresidence plugin environment or using security plugins that enforce stricter authorization checks until a patch is applied.
