Site isolation is a security feature designed to separate different websites into different processes to prevent data leakage. The CVSS 3.1 base score is 8.8, indicating high impact with network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high confidentiality, integrity, and availability impacts. The vendor advisory link is provided but does not explicitly confirm patch availability or remediation status.

Successful exploitation allows a remote attacker to bypass Chrome's site isolation, potentially leading to unauthorized access to sensitive data across site boundaries. The impact includes high confidentiality, integrity, and availability risks as indicated by the CVSS vector. No known exploits in the wild have been reported to date.
