Please enable private security vulnerability reporting

[FeldrinH]

I would like to report a security vulnerability in this library. To avoid abuse of this vulnerability before it has been fixed I would like to do it privately.

Please enable private security vulnerability reporting for this repo (see https://docs.github.com/en/code-security/security-advisories/repository-security-advisories/configuring-private-vulnerability-reporting-for-a-repository) or provide me with a contact for reporting security issues.
