- The project / component that contains the reported vulnerability.
- A description of the vulnerability. In particular, the type of the
   reported vulnerability and how it might be exploited. Alternatively,
   a well-established vulnerability identifier, e.g. CVE number, can be
   used instead.

Based on the description mentioned above, a MinIO engineer or security team
member investigates:

- Whether the reported vulnerability exists.
