Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a user to actively navigate to an attacker-controlled HTML page using a vulnerable Chrome version (below 152.0.7977.65) - the CVSS UI:R metric confirms passive drive-by exploitation without user navigation is not applicable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 score reflects a network-reachable, low-complexity attack requiring no privileges but mandatory user interaction (UI:R), scoped to the vulnerable system with integrity-only impact (I:L, C:N, A:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that exploits the incorrect authorization in Chrome's Select component to bypass same-origin policy restrictions. When a victim using a vulnerable Chrome version navigates to the page - via a phishing link, malvertising redirect, or compromised site - the attacker's script performs limited unauthorized cross-origin integrity actions within the user's browsing session. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch as documented in the stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
