HCsCR is a Minecraft mod. Proper security in this realm is a rare occasion. Additionally, the niche/role of HCsCR isn't very prone to vulnerabilities. However, if you think the bug you have found is a vulnerability, you can report it privately via any of the following methods:

• GitHub Private vulnerability reporting: Head over to the Security tab and click "Report a vulnerability".
• Mail: imvidtu <at> proton <dot> me

Where possible, prefer GitHub Private vulnerability reporting.

The only supported versions for vulnerability reporting are:

• The latest release published to Modrinth and/or GitHub.
• The latest pre-release published to GitHub¹.
• The latest alpha and/or beta published to Modrinth[1].
• The latest Git commit build.
