CVE-2023-6624: Import and export users and customers <= 1.24.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via shortcode

The Import and export users and customers plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 1.24.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

This is a stored cross-site scripting issue in a WordPress user import/export plugin. A logged-in user with Contributor-level access or higher could save malicious script through plugin shortcode attributes. That script could later run for visitors who open the affected page, creating confidentiality and integrity risk.

Executive priority

Treat as a controlled but real website security issue. It is not known to be actively exploited from the supplied sources, but affected public WordPress sites should be patched or the plugin disabled during normal security maintenance.

Technical view

CVE-2023-6624 affects Import and export users and customers for WordPress through version 1.24.3. The issue is insufficient sanitization and output escaping of user-supplied shortcode attributes, classified as CWE-79. CVSS 3.1 is 4.9 with low confidentiality and integrity impact, changed scope, and no availability impact.

Likely exposure

Exposure is limited to WordPress sites using this plugin at version 1.24.3 or earlier, where Contributor or higher accounts can create content using the vulnerable shortcode. Sites with many content authors or weak account governance face higher practical risk.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Abuse requires authenticated Contributor-level or higher access and an injected page being accessed. Business impact depends on who views affected pages and what browser/session context is exposed.

Researcher notes

The key research angle is shortcode attribute handling and escaping behavior in versions through 1.24.3. The supplied WordPress Trac changeset is relevant for patch review, but no exploit confirmation is included. Avoid assuming broader plugin functions are affected without source evidence.

Mitigation direction

  • Update the plugin to a version newer than 1.24.3 if vendor guidance confirms availability.
  • If no fixed version is available, disable or remove the plugin until remediated.
  • Restrict Contributor and higher accounts to trusted users only.
  • Review and sanitize existing pages using the plugin shortcodes.
  • Monitor vendor, WordPress plugin, and Wordfence advisories for fix details.

Validation and detection

  • Inventory WordPress sites for the Import and export users and customers plugin.
  • Confirm installed plugin versions are not 1.24.3 or earlier.
  • Review content containing plugin shortcodes for unexpected attributes or scripts.
  • Audit Contributor, Author, Editor, and Administrator accounts for necessity.
  • Confirm remediation in staging before production deployment.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
