WordPress vulnerability analysis and mitigation
Overview
CVE-2021-25066 is a security vulnerability affecting the Ninja Forms WordPress plugin versions below 3.6.10. The vulnerability was discovered in the plugin's form import functionality, where insufficient data sanitization could lead to Cross-Site Scripting (XSS) attacks (WPScan).
Technical details
The vulnerability stems from improper sanitization and escaping of imported data in the Ninja Forms plugin. This security flaw allows users with high privileges to execute Cross-Site Scripting attacks, even in environments where the unfiltered_html capability is explicitly disabled (WPScan).
Impact
The vulnerability enables authenticated users with administrative privileges to perform stored Cross-Site Scripting attacks through the form import functionality. This could potentially lead to the execution of malicious scripts in the context of other users' browsers who access the affected forms (WPScan).
Mitigation and workarounds
The recommended mitigation is to update the Ninja Forms plugin to version 3.6.10 or later, which contains the security fix for this vulnerability (Wordfence).
