To report vulnerabilities, you can privately report a potential security issue via the GitHub security vulnerabilities feature. This can be done here: https://github.com/dmf-mxl/mxl/security/advisories
Please do not open a public issue about a potential security vulnerability. You can find more details on the security vulnerability feature in the GitHub documentation here: https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing/privately-reporting-a-security-vulnerability
