Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required (UI:R): the victim must actively visit or be redirected to a specifically crafted HTML page in an unpatched Chrome browser - passive network exposure alone is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.5 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H) accurately reflects a high-impact but difficult-to-reliably-trigger vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing JavaScript designed to win a specific V8 engine race window - for example, triggering concurrent garbage collection and object access - and distributes the link via phishing email or malvertising. When a target visits the page in an unpatched Chrome instance and the race condition fires, the attacker gains arbitrary code execution within the Chrome renderer process sandbox. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later - this is the vendor-released patch as documented in the Chrome Stable Channel update 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. |
