【Security】： security issue report

Hi maintainers,

I have identified a potential security issue in tig and would like to report it responsibly.

I could not find a SECURITY.md file or a documented vulnerability disclosure process for this repository. I also do not want to disclose technical details, reproduction steps, or proof-of-concept information publicly in a GitHub issue.

Could you please let me know the preferred private channel for reporting security issues, or enable GitHub private vulnerability reporting for this repository?

I can provide the following privately:

• affected files and versions/commit ranges
• impact assessment and severity
• reproduction steps
• proof-of-concept evidence
• recommended remediation options

Thanks.
