 In order to report a security vulnerability, you can use [GitHub's built-in tool](https://github.com/0x5bfa/FluentHub/security/advisories/new) which easily allows you to calculate an _attack vector/CVSS string_ or attribute to an existing [`CVE`](https://cve.org) code. This allows the FluentHub Team to accurately calculate the severity and/or importance of preventing it.
