Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must induce the target user to visit a crafted HTML page using a vulnerable Chrome version (prior to 152.0.7977.65) - user interaction is mandatory (UI:R per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N scores 6.5, reflecting low attack complexity and no required privileges but mandatory user interaction - the victim must visit a crafted page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A threat actor hosts a crafted HTML page containing JavaScript that triggers the DOM authorization bypass to read sensitive cross-origin or privileged DOM properties. The victim is lured via phishing or malvertising to navigate to the page in a vulnerable Chrome version; upon render, the script silently exfiltrates accessible data without requiring any further user action beyond the initial page visit. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later via the browser's built-in update mechanism (Help > About Google Chrome) or the stable channel release documented at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
