Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to install a crafted Chrome extension on a system running Google Chrome prior to 153.0.8010.36, making user interaction (UI:R) a hard prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 score, scope-unchanged flag (S:U), and integrity-only impact (C:N/I:H/A:N) position this as a moderate-severity authorization bypass rather than a critical remote compromise. … 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. |
