What this covers

This feed accumulates forward from the day it started storing records, and a name search that finds nothing here is also looked up against the registers directly — so an older advisory resolves even when it predates the corpus. It is still a reading view, not a substitute for the vendor's own advisory, and absence from this page is not a statement that Flow is free of vulnerabilities.
