Please report security issues privately, through GitHub's private vulnerability reporting: open the affected repository's Security tab and choose Report a vulnerability. Do not open a public issue.
Include what is affected, how to reproduce it, and its impact as you understand it. You will get an acknowledgement, and a fix or a plan, as soon as the maintainers can provide one; the issue is disclosed publicly once a fix is released.
densa is at 0.x: only the latest release (and the main branch) receives fixes.
