Found a vulnerability?
If you would rather not deal with the vendor yourself, a BugRater analyst will submit it upstream on your behalf, with your explicit permission, and tell you what came back.
Ask BugRater to submit itPrivate. The report body is encrypted at rest; BugRater holds the key, so the analyst working it can read it. Every read is logged.
