Quota was not necessarily money received

The maintainer's April advisory lists versions before v0.12.10 as affected and v0.12.10 as patched. It describes payment-callback validation failures that could grant quota without payment and leave the operator paying upstream model costs.

A setup fee does not settle the maintenance question

The project's security policy supports the latest version and provides a private vulnerability-reporting route. Our operational takeaway is to agree who tracks updates, tests payment reconciliation and handles incidents before selling prepaid balances. This is a checklist inferred from the documented risk, not evidence against a seller.
