CVE-2023-4239: 
WordPress vulnerability analysis and mitigation

The Real Estate Manager plugin for WordPress contains a privilege escalation vulnerability (CVE-2023-4239) discovered in versions up to and including 6.7.1. The vulnerability was publicly disclosed on August 8, 2023, and affects the plugin's profile update functionality. This security issue stems from insufficient restrictions in the 'remsaveprofile_front' function (CVE MITRE, NVD NIST).

The vulnerability exists due to improper validation of user metadata in the 'remsaveprofile_front' function. The CVSS v3.1 base score ranges from 6.5 (MEDIUM) according to NVD to 8.8 (HIGH) according to Wordfence, with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. The issue is classified under CWE-269, which relates to improper privilege management (NVD NIST).

The vulnerability allows authenticated users with minimal permissions (such as subscribers) to modify their user role by manipulating the 'wp_capabilities' parameter during profile updates. This could potentially enable attackers to escalate their privileges to administrator level, giving them full control over the WordPress site (WPScan).

As of the latest reports, there is no known fix available for this vulnerability. Website administrators using the Real Estate Manager plugin should consider implementing additional security measures or temporarily disabling the plugin until a patch is released (WPScan).
