WordPress · Members Import · CVE-2022-4663
**Name of the Vulnerable Software and Affected Versions**
Members Import plugin for WordPress versions up to, and including, 1.4.2
**Description**
The issue is related to Self Cross-Site Scripting via the `user login` parameter in an imported CSV file due to insufficient input sanitization and output escaping. This allows attackers to inject arbitrary web scripts in pages that execute if they can trick a site's administrator into uploading a CSV file with the malicious payload.
**Recommendations**
For versions up to, and including, 1.4.2, consider disabling the import functionality of the Members Import plugin until a patch is available, and restrict access to uploading CSV files to minimize the risk of exploitation. As a temporary workaround, avoid using the `user login` parameter in imported CSV files until the issue is resolved.
