CVE-2022-30334 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

Brave before 1.34, when a Private Window with Tor Connectivity is used, leaks .onion URLs in Referer and Origin headers. NOTE: although this was fixed by Brave, the Brave documentation still advises "Note that Private Windows with Tor Connectivity in Brave are just regular private windows that use Tor as a proxy. Brave does NOT implement most of the privacy protections from Tor Browser."
