CVE-2026-13871

Description Insufficient policy enforcement in GuestView allows a remote attacker who has compromised the renderer process to bypass site isolation through the use of a crafted HTML page. Site isolation is a security mechanism that ensures pages from different sites are run in separate processes to prevent data theft.
