AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability occurs in Brave Browser Desktop versions prior to 1.83.10 when the split view feature is enabled. The "Open Link in Split View" context menu item does not respect the SameSite cookie attribute, causing SameSite=Strict cookies to be sent during cross-site navigation using this method, which should not normally happen.
How can this vulnerability impact me? :
The vulnerability can lead to SameSite=Strict cookies being sent on cross-site navigations, potentially exposing sensitive cookie data to unintended sites. This can increase the risk of cross-site request forgery (CSRF) or other cross-site attacks, compromising user privacy and security.
