CVE-2023-7203: 
WordPress vulnerability analysis and mitigation

The Smart Forms WordPress plugin before version 2.6.87 contains a vulnerability related to missing authorization in various AJAX actions. The vulnerability was discovered and disclosed on February 2, 2024, affecting all versions of the Smart Forms plugin prior to 2.6.87. This security issue impacts WordPress installations using the affected versions of the Smart Forms plugin (WPScan, NVD).

The vulnerability stems from insufficient authorization checks in various AJAX actions within the plugin. This security flaw allows users with roles as low as subscriber to call these AJAX actions and perform unauthorized operations, such as deleting entries. Additionally, the plugin lacks CSRF (Cross-Site Request Forgery) checks in certain areas, which compounds the security risk. The vulnerability has been assigned a CVSS v3.1 base score of 6.1 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (NVD).

The vulnerability allows unauthorized users to perform administrative actions, specifically the ability to delete entries from forms. This could lead to data loss and disruption of form functionality on affected WordPress sites. The impact is particularly concerning as it allows users with minimal privileges to perform actions that should be restricted to administrators (WPScan).

The recommended mitigation is to update the Smart Forms plugin to version 2.6.87 or later, which includes fixes for these security issues. Site administrators should prioritize this update to prevent unauthorized access and potential data manipulation (WPScan).
