CVE-2025-68071 is an authorization bypass vulnerability identified in the g5theme Essential Real Estate WordPress plugin, affecting versions up to and including 5.2.2. The root cause is an incorrectly configured access control mechanism that allows an attacker with limited privileges (PR:L) to manipulate a user-controlled key parameter to bypass authorization checks. This vulnerability falls under CWE-639, which relates to authorization errors due to improper access control. The CVSS 3.1 base score is 6.5, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). This means an attacker who has some level of authenticated access can exploit this flaw remotely without user interaction to gain unauthorized access to sensitive information. Although no public exploits are currently known, the vulnerability poses a significant risk to confidentiality, potentially exposing sensitive real estate data or user information managed by the plugin. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps. The vulnerability is particularly concerning for organizations relying on this plugin for managing real estate listings and client data, as unauthorized access could lead to data breaches or privacy violations.

For European organizations, especially those in the real estate sector using WordPress with the Essential Real Estate plugin, this vulnerability could lead to unauthorized disclosure of sensitive client and property data. The confidentiality impact is high, which could result in regulatory non-compliance under GDPR due to exposure of personal data. Although integrity and availability are not directly affected, the breach of confidentiality can damage organizational reputation and client trust. Attackers with low-level privileges could escalate their access, potentially leading to further exploitation within the network. The medium severity rating indicates a moderate but tangible risk that requires timely attention. Given the widespread use of WordPress in Europe and the popularity of real estate online platforms, the potential attack surface is significant. Organizations failing to address this vulnerability may face legal, financial, and operational consequences.

1. Immediately audit and review access control configurations within the Essential Real Estate plugin to ensure that user-controlled keys or parameters cannot be manipulated to bypass authorization. 2. Restrict plugin access to only trusted users with necessary privileges and implement the principle of least privilege. 3. Monitor logs for unusual access patterns or attempts to exploit authorization mechanisms. 4. Apply any available patches or updates from the vendor as soon as they are released. 5. If patches are not yet available, consider temporarily disabling the plugin or restricting its functionality to mitigate risk. 6. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable parameters. 7. Educate administrators and developers about secure plugin configuration and the risks of improper access control. 8. Conduct penetration testing focused on authorization bypass scenarios to identify and remediate similar weaknesses. 9. Maintain regular backups and incident response plans to quickly recover from potential breaches.
