==Severity Ratings ==
Severity ratings are used to indicate how severe we beleive believe a bug is, and help provide guidance for its urgency and priority. Generally, we ask that they only be assigned by those with experience evaluating vulnerabilities in coordination with the security team. Presently we meet weekly to triage unclassified bugs.
