CVE-2025-48980

In Brave Browser Desktop versions prior to 1.83.10 that have the split view feature enabled, the "Open Link in Split View" context menu item did not respect the SameSite cookie attribute.

MEDIUM 6.5EPSS 0.33%

Does this matter?

Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.

Description

In Brave Browser Desktop versions prior to 1.83.10 that have the split view feature enabled, the "Open Link in Split View" context menu item did not respect the SameSite cookie attribute. Therefore SameSite=Strict cookies would be sent on a cross-site navigation using this method.
