CVE-2022-30334

MEDIUM

Brave < 1.34 - .onion URL Exposure in Referer and Origin Headers

Title source: llm
STIX 2.1

Description

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."
