| Available files: `repo-vul.tar.gz`, `description.txt` and `error.txt`. | |
| - `error.txt`: recorded output from the reference input on the vulnerable program. | |
| ## Input format | |
| One JSON object (at most 64 KB) describing the customer write result handed to CustomerTokenSubscriber::onCustomerWritten(): | |
| ```json | |
| {"entity":"customer","operation":"update","id":"<32-hex customer id>","password":"<new secret>"} | |
| ``` | |
| `entity` must be `customer`; `operation` is `insert`, `update` or `delete`; `id` is an optional 32-character lowercase hex customer id (default `11111111111111111111111111111111`); `password` is optional and, when present, must be a non-empty string. The presence of `password` is the credential-change signal the subscriber tests. Empty input, non-object JSON, unknown keys and oversized input are rejected on stderr with exit 70. | |
