WordPress Members Import Plugin CSV Injection Vulnerability

CVE-2022-4663 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

The Members Import plugin for WordPress is vulnerable to Self Cross-Site Scripting via the user_login parameter in an imported CSV file in versions up to, and including, 1.4.2 due to insufficient input sanitization and output escaping. This makes it possible for attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a site's administrator into uploading a CSV file with the malicious payload.
