Qt vulnerabilitiesRanked by how likely they are to be used.
Qt is made by Digia. We track 9 published vulnerabilities in it, across 68 versions. None of them is on the list of flaws known to be exploited today. If you run Qt, keep it on a version the vendor still supports.
We keep watching the known-exploited list.
Which Qt vulnerabilities are being exploited?
This is the list that matters most: flaws criminals are using now.

Which Qt flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
