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.Show less

Prior to commit 51867e0d15a6d7f80d5b714fd0e9976b9c160bb0, https://github.com/brave/adblock-lists removed redirect interceptors on some websites like Facebook in which the redirect interceptor may have been there for security purposes. This could potentially cause open redirects on these websites. Brave's redirect interceptor removal feature is known as "debouncing" and is intended to remove unnecessary redirects that track users across the web.Show less

Brave Browser before 1.43.88 allowed a remote attacker to cause a denial of service in private and guest windows via a crafted HTML file that mentions an ipfs:// or ipns:// URL. This is caused by an incomplete fix for CVE-2022-47932 and CVE-2022-47934.Show less

Brave Browser before 1.42.51 allowed a remote attacker to cause a denial of service via a crafted HTML file that references the IPFS scheme. This vulnerability is caused by an uncaught exception in the function ipfs::OnBeforeURLRequest_IPFSRedirectWork() in ipfs_redirect_network_delegate_helper.cc.Show less

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."Show less

In Brave Desktop 1.17 through 1.33 before 1.33.106, when CNAME-based adblocking and a proxying extension with a SOCKS fallback are enabled, additional DNS requests are issued outside of the proxying extension using the system's DNS settings, resulting in information disclosure. NOTE: this issue exists because of an incomplete fix for CVE-2021-21323 and CVE-2021-22916.Show less

In Brave Desktop between versions 1.17 and 1.26.60, when adblocking is enabled and a proxy browser extension is installed, the CNAME adblocking feature issues DNS requests that used the system DNS settings instead of the extension's proxy settings, resulting in possible information disclosure.Show less

Brave is an open source web browser with a focus on privacy and security. In Brave versions 1.17.73-1.20.103, the CNAME adblocking feature added in Brave 1.17.73 accidentally initiated DNS requests that bypassed the Brave Tor proxy. Users with adblocking enabled would leak DNS requests from Tor windows to their DNS provider. (DNS requests that were not initiated by CNAME adblocking would go through Tor as expected.) This is fixed in Brave version 1.20.108Show less

The implementation of Brave Desktop's privacy-preserving analytics system (P3A) between 1.1 and 1.18.35 logged the timestamp of when the user last opened an incognito window, including Tor windows. The intended behavior was to log the timestamp for incognito windows excluding Tor windows. Note that if a user has P3A enabled, the timestamp is not sent to Brave's server, but rather a value from:Used in last 24hUsed in last week but not 24hUsed in last 28 days but not weekEver used but not in last 28 daysNever usedThe privacy risk is low because a local attacker with disk access cannot tell if the timestamp corresponds to a Tor window or a non-Tor incognito window.Show less

Brave Software Inc. Brave version version 0.22.810 to 0.24.0 contains a Other/Unknown vulnerability in function ContentSettingsObserver::AllowScript() in content_settings_observer.cc that can result in Websites can run inline JavaScript even if script is blocked, making attackers easier to track users. This attack appear to be exploitable via the victim must visit a specially crafted website. This vulnerability appears to have been fixed in 0.25.2.Show less

A hang issue was discovered in Brave before 0.14.0 (on, for example, Linux). This vulnerability is caused by the mishandling of a long URL formed by window.location+='?\u202a\uFEFF\u202b'; concatenation in a SCRIPT element.Show less

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).Show less
