Security Disclosure Contact Request

[NetGakarot]

Hello team,

I attempted to responsibly disclose two security findings privately via security@gitbank.io, but the email address rejected external mail with:
554 5.7.1 Relay access denied

Could someone please provide a working private security disclosure channel or alternative contact method?
No vulnerability details are being disclosed publicly.

Thank you.
