CVE-2024-6687Network attack vector

Unauthenticated customer data exposure via public files

Published Aug 1, 2024 · Updated Apr 8, 2026

Information exposure in CTT Expresso para WooCommerce 3.2.12 and earlier allows remote attackers to read customer data from public files. The plugin writes generated shipping PDFs and logs containing names, phone numbers, postal addresses, and email addresses beneath /wp-content/uploads/cepw without preventing unauthenticated web access. No account or user interaction is required; an attacker who locates the generated files can read their contents, while no write or service-interruption impact is reported.
