Brave Browser before 1.59.40 does not properly restrict the schema for WebUI factory and redirect. This is related to browser/brave_content_browser_client.cc and browser/ui/webui/brave_web_ui_controller_factory.cc.
An Open Redirect vulnerability exists prior to version 1.52.117, where the built-in QR scanner in Brave Browser Android navigated to scanned URLs automatically without showing the URL first. Now the user must manually navigate to the URL.
Brave Software's Brave Browser, version 0.19.73 (and earlier) is vulnerable to an incorrect access control issue in the "JS fingerprinting blocking" component, resulting in a malicious website being able to access the fingerprinting-associated browser functionality (that the browser intends to block).
