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.
These are HackerOne’s own figures for this program, taken from its public page. Researchers did not report them, and they don't count toward the BugRater grade. Captured 7 Nov 2026.
What it pays, by severity
$153,513 paid to researchers in total, $25,895 of it in the last 90 days. This is HackerOne’s lifetime figure. It shows the program has paid out before. It doesn't tell you what any one report will get.
