CVE-2022-4663: Members Import <= 1.4.2 - Self Cross-Site Scripting

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.

Security readout for executives and security teams

Plain-English summary

This affects the WordPress Members Import plugin through version 1.4.2. If an administrator imports a malicious CSV, script code in a login field may run in the administrator’s browser. The issue is constrained by needing administrator import action, but it can still expose or alter limited data in that browser context.

Executive priority

Treat as moderate priority. It is not remotely exploitable without administrator action, but it affects an administrative workflow and can create browser-based compromise risk during imports.

Technical view

CVE-2022-4663 is a CWE-79 self cross-site scripting flaw in Members Import. The source identifies insufficient sanitization and output escaping of the user_login parameter from imported CSV data. CVSS is 5.5 with high privileges required and changed scope. The bundle does not name a fixed version.

Likely exposure

Exposure is limited to WordPress sites using Members Import versions up to and including 1.4.2, especially where administrators import CSV files from untrusted or weakly controlled sources.

Exploitation context

The bundle does not show KEV listing or active exploitation evidence. Exploitation depends on convincing a site administrator to upload a crafted CSV file. No exploit details should be needed to validate exposure.

Researcher notes

Core facts are source-grounded, but metadata is incomplete: the affected array is sparse while the title and description state versions through 1.4.2. No patch, fixed version, or exploitation evidence is provided in the bundle.

Mitigation direction

  • Inventory WordPress sites for the Members Import plugin and version.
  • Check vendor or WordPress plugin guidance for a fixed release or replacement.
  • Disable or remove the plugin if CSV member imports are not required.
  • Restrict CSV imports to trusted administrators and trusted file sources.
  • Review admin import procedures for external or user-supplied CSV files.

Validation and detection

  • Confirm whether Members Import is installed on each WordPress site.
  • Verify whether the installed version is 1.4.2 or earlier.
  • Review recent administrator CSV import activity and file provenance.
  • Check whether imported login values are safely escaped in rendered pages.
  • Document any sites where plugin status or version cannot be confirmed.
