Reporting a vulnerability

If you believe you have found a security issue in OSN infrastructure or datasets, write to us with the affected system and the steps to reproduce it. Please do not include personal data in reports.

We follow coordinated disclosure: we confirm receipt, keep you informed while we investigate, and credit reporters who want to be named.
