Asset
Public Others Target The specific asset the finding landed against, as the platform named it.
Severity
high Bugcrowd rates P1–P5; this is that rating in HackerOne's words so the two feeds can sit in one table.
Award
Not published This does not mean nothing was paid. Both platforms let a programme accept a finding without publishing the figure, and most do.

Where this came from. One row of a public platform feed, stored as published and never edited. We hold no report title, no write-up and no reproduction steps, because the feeds do not carry them and we do not go looking for them. A withheld name stays withheld; if a finder later asks the platform to un-name them, the next sweep un-names them here. Absence of an award figure is publication policy, not evidence a programme did not pay.
