- **Complexity:** Low to Medium.
- **Attack Vector:** Network (Remote). Usually triggered by a user visiting a specially crafted malicious website.
## Impact
- **Confidentiality:** High (Potential for data theft if code execution is achieved).
- **Integrity:** High (Potential for unauthorized modification of system files/browser data).
- **Availability:** High (Potential for application crashes or total system compromise).
## Remediation
### Patches
Update Google Chrome to the following versions or later:
- **Windows/Mac:** 149.0.7827.53/54
