CVE-2024-4734: Import and export users and customers <= 1.26.6.1 - Authenticated (Administrator+) Stored Cross-Site Scripting
The Import and export users and customers plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.26.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfilteredhtml has been disabled.
