Vulnerability AssessmentAI
| Exploitation | Victim must be running Google Chrome prior to 153.0.8010.36 on a desktop platform and must interact with crafted network traffic (UI:R) - for example, visiting an attacker-controlled page or being subject to a network-level traffic injection. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N describes a network-exploitable, low-complexity flaw requiring no attacker authentication but necessitating victim user interaction - the most significant limiting factor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome to version 153.0.8010.36 or later, which addresses the incorrect authorization logic in the DeviceBoundSessionCredentials component. … Detailed patch versions, workarounds, and compensating controls in full report. |
