Please keep the following in mind
-
Provide detailed information: describe the vulnerability as precisely as possible, including the steps to reproduce it. This helps us understand the problem faster and fix it sooner.
-
Do not share the vulnerability with others: do not disclose anything publicly until we have had the chance to fix the problem. This prevents malicious parties from exploiting it.

Please be patient: it may take some time to fully investigate and fix the vulnerability. You will hear from us as soon as we know more.
