The WP RealEstate WordPress plugin version 1.6.26 or earlier contains an uncontrolled privilege escalation flaw in the "process_register" function. Unauthenticated users can submit a registration request that is processed without proper role checks, creating a new account assigned the Administrator role. This flaw allows a malicious actor to gain full administrative access to the entire site, including content management, plugin configuration, and user data, without any authentication prerequisite.

ApusThemes WP RealEstate plugin used by the Homeo theme is affected. All plugin versions up to and including 1.6.26 are vulnerable. No other product versions are known to be impacted.

The CVSS score of 9.8 reflects the catastrophic impact of the vulnerability. The EPSS score of less than 1% indicates that publicly known exploitation is currently rare, but the absence of the vulnerability from CISA's KEV catalog does not mitigate the risk. An attacker can exploit the flaw via a standard HTTP request to the process_register endpoint, with no prerequisite credentials. Because the exploit creates an administrator account, the entire site can be fully compromised once this vulnerability is leveraged.
