Analysis

Impact

The vulnerability is an inappropriate input handling in the Chrome renderer on Android that allows a remote attacker who has already compromised the renderer process to serve a crafted HTML page that bypasses the browser’s site isolation boundaries. The flaw is classified as CWE-20 and removes the isolation that protects different web origins from each other. Based on the description, it is inferred that the attacker and the compromised renderer must already be in place for the exploit to succeed.

Affected Systems

Google Chrome for Android versions earlier than 150.0.7871.47 are within the scope. Newer releases contain the control that mitigates the bypass.

Risk and Exploitability

The CVSS score of 6.5 indicates medium severity, and the EPSS score of less than 1% indicates a low probability of exploitation. The vulnerability is not listed in the CISA KEV database.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
