CVE-2026-104368: Export and Import Users and Customers plugin privilege escalation

CVE-2026-104368 · Severity: high · CVSS 8.8 · Published 2026-10-30

The Export and Import Users and Customers plugin for WordPress allows authenticated Subscriber-level users to escalate their privileges to Administrator by injecting malicious data during the export-import workflow. An attacker can craft a biographical information field containing a special character sequence that causes the CSV parser to create a fake user record with administrative access. This allows account takeover and full website compromise.

Vendors: WordPress.org.

Technical details

The vulnerability is a CSV escape-character mismatch between the exporter (using backslash escape) and importer (using double-quote escape) in class-csvwriter.php and class-csvreader.php. An authenticated attacker with Subscriber-level access can inject a crafted backslash-quote-newline sequence in the Biographical Info field, causing the CSV importer to parse the injected payload as a new user record with attacker-controlled login, password, email, and role, enabling arbitrary Administrator account creation.
