## Affected

- reepaydenmark Frisbii Pay: through 1.8.9

## Description

The Frisbii Pay plugin for WordPress is vulnerable to unauthorized modification of data due to missing capability checks on the 'upload_csv' and 'process_batch' functions in all versions up to, and including, 1.8.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary CSV data and overwrite WooCommerce payment tokens, postmeta, and order meta records.
