Security Policy

If you find a security issue or vulnerability, please do not open a public Issue or Pull Request.

Instead, please report it privately via one of these two methods:

  1. Complete the Google Form. Set the Inquiry Category to "Security Issue with a GitHub Repository of @tyleruploads", and start the inquiry with the name of this repository (devtkit).
  2. Email me at tyleruploads@yahoo.com.

Note on Response Times

This is a small, solo project maintained by a middle school student in my spare time. Because of this, I may not be immediately available, and the issue may take some time to be resolved. There is a period of time in the year when I generally will not be able to be contacted, from near the end of June until around one month later. During that period, issues will not be addressed. Thank you for your patience and eagerness to improve the security of this project!
