Summary
Malicious code in saeka (PyPI)
Details

When a user invokes the card-checking feature, saeka sends the supplied card number, expiration month and year, and CVV as a single value to https://uncoder.eu.org/cc-checker/api.php using an HTTP POST. The package description does not disclose this external recipient or the transfer of complete card credentials. Versions 8.0 through 15.0 listed below contain this behavior. The request requires use of the checking feature; installation or import alone does not trigger it. Version 15.0 also includes bulk card checking and a Shopify checkout flow. The recipient's ownership, retention of submitted data, and any actual unauthorized transactions have not been established.
