CVE-2026-3462Network attack vector

Subscriber-level payment data overwrite via unchecked CSV processing

Published Jun 27, 2026 · Updated Jun 27, 2026

Missing authorization in Frisbii Pay 1.8.9 and earlier allows remote authenticated users to overwrite WooCommerce payment data. The upload_csv function accepts attacker-supplied CSV data, and process_batch writes its rows into payment token, postmeta, and order meta records without verifying the caller's capability. Subscriber-level access is sufficient, and exploitation changes stored payment and order metadata without reported confidentiality or availability impact.
