Found a vulnerability?
If you'd rather not deal with the vendor yourself, a BugRater analyst will submit it to them for you, with your explicit permission, and tell you what they said.
Ask BugRater to submit itReports are private. The report body is encrypted at rest. BugRater holds the key, so the analyst handling your report can read it, and we log every time someone does.
