CVE-2021-22917
Brave Browser Desktop between versions 1.17 and 1.20 is vulnerable to information disclosure by way of DNS requests in Tor windows not flowing through Tor if adblocking was enabled.
Does this matter?
Lower severity and a low EPSS score (1.23%). Track it; it rarely justifies an emergency change on its own.
