CVE-2023-38386: 
WordPress vulnerability analysis and mitigation

A Missing Authorization vulnerability (CVE-2023-38386) was discovered in Saturday Drive's Ninja Forms WordPress plugin affecting versions through 3.6.25. The vulnerability was disclosed on July 25, 2023, and was patched in version 3.6.26. This security flaw affects over 800,000 WordPress sites using the Ninja Forms plugin (Hacker News, Patchstack).

The vulnerability is classified as a broken access control issue with a CVSS v3.1 Base Score of 7.6 (High), with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L. The flaw exists in the form submissions export feature, allowing users with Contributor privileges to access and export all Ninja Forms submissions on a WordPress site (Patchstack Database).

The vulnerability allows users with Contributor role access to export all form submissions on a WordPress site, potentially leading to unauthorized access to sensitive information submitted through Ninja Forms (Hacker News).

The vulnerability requires an attacker to have at least Contributor-level access to the WordPress site. The broken access control in the export_listen function allows exploitation through the /wp-admin/edit.php endpoint, as there was no proper permission check implemented (Patchstack).

Users are strongly recommended to update to Ninja Forms version 3.6.26 or later, which includes patches for this vulnerability. The vendor has implemented proper permission checks to prevent unauthorized access to the form submission export functionality (Patchstack).
