Report privately through GitHub's vulnerability reporting or email andrew@zealsprince.com. If you'd rather reach me somewhere else, zealsprince.com links out to everywhere I'm active. Don't open a public issue for anything exploitable. You'll hear back within a week, and you'll be credited in the fix unless you'd rather not be.
