Preferred security contact for reporting security vulnerability

Hello,
I’ve found a vulnerability in YJS, and, following Github guidance about disclosing vulnerabilities in the industry I’m asking your preferred security contact details so I can share with you the report and collaborate on a fix.
Thanks,

Just send a mail to <kevin.jahns at pm.me>

I think you already did that. Sorry I didn’t get back to you. I’ll be in touch ASAP
