CVE-2026-10782 in RealHomes Memberships Plugin
Summary
by MITRE • 08/01/2026
The RealHomes Memberships plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.0.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to grant themselves any premium membership tier without completing a PayPal transaction, generating a falsified active payment receipt and gaining unauthorized access to restricted property listing allowances.

The RealHomes Memberships plugin for WordPress presents a critical authorization bypass vulnerability that affects all versions up to and including 3.0.9, representing a significant security weakness in the plugin's access control mechanisms. This vulnerability stems from improper user authorization verification within the plugin's core functionality, where the system fails to adequately validate user permissions before granting membership privileges. The flaw exists at the application level and specifically impacts the plugin's membership tier assignment process, creating a pathway for unauthorized privilege escalation that directly violates fundamental security principles of least privilege and proper access control enforcement.
The technical implementation of this vulnerability allows authenticated attackers who possess subscriber-level access or higher to exploit a logical flaw in the membership validation workflow. When users attempt to upgrade their membership status, the plugin does not properly verify whether the user has legitimate authorization to perform such actions, particularly when bypassing payment processing requirements. This authorization bypass enables malicious actors to manipulate the membership tier assignment system by directly setting their account status to premium levels without completing required payment transactions. The vulnerability essentially removes the payment verification step from the membership upgrade process, allowing attackers to generate falsified active payment receipts that appear legitimate within the plugin's internal systems.
The operational impact of this vulnerability extends beyond simple unauthorized access to include potential financial fraud and service abuse scenarios. Attackers can leverage this flaw to gain unrestricted access to premium property listing allowances that would normally require payment processing, effectively providing them with enhanced capabilities within the RealHomes platform. This unauthorized access could result in increased resource consumption through excessive property listings, potential data exposure from privileged access to restricted content, and financial losses for the plugin vendor due to unauthorized premium memberships. The vulnerability creates a persistent threat vector that remains active as long as the vulnerable plugin version is installed on WordPress sites.
This vulnerability aligns with CWE-285, which addresses improper authorization in software systems, and represents a clear violation of the principle of proper access control validation. From an attacker perspective, this issue maps to ATT&CK technique T1078 for valid accounts and T1566 for credential harvesting, as it allows unauthorized users to escalate privileges without requiring additional authentication methods. The vulnerability demonstrates poor input validation and insufficient privilege checking mechanisms within the plugin's membership management system. Organizations should immediately implement mitigations including immediate plugin updates to versions that address this authorization bypass, implementing additional access controls at the WordPress level, monitoring user activity for suspicious membership changes, and considering temporary deactivation of the plugin until proper security patches are deployed across all affected installations.
The remediation approach must include comprehensive patch management procedures to ensure all vulnerable WordPress installations receive timely updates from the plugin vendor. Additionally, system administrators should implement network-based controls to monitor for unusual membership tier changes and establish automated alerts when premium access is granted without corresponding payment processing records. Organizations should also consider implementing role-based access controls within WordPress that limit the scope of actions available to subscriber-level users and maintain detailed audit logs of all membership-related activities to detect potential exploitation attempts and support forensic analysis if incidents occur.
