Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open a crafted HTML page in an unpatched Google Chrome before 149.0.7827.197 - the user-interaction requirement (UI:R) means the attacker must lure the user to attacker-controlled content; it cannot be triggered without that page load. … 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:H/I:H/A:H, 8.8 High) indicates network-reachable, low-complexity exploitation with no privileges but requiring user interaction, and unchanged scope with total impact to confidentiality, integrity, and availability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or compromises an ad/iframe on a legitimate site) containing crafted HTML and JavaScript that triggers the Blink use-after-free, then entices a victim to visit it via phishing or malvertising. When the page loads in an unpatched Chrome, the dangling pointer is reclaimed with attacker-controlled data, yielding arbitrary code execution within the renderer sandbox. … |
| Remediation | Vendor-released patch: 149.0.7827.197 - update Google Chrome to 149.0.7827.197 or later via the Chrome Releases stable channel update (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0482630350.html), then fully relaunch the browser to apply the new build since Chrome only loads the updated binary after a restart. … Detailed patch versions, workarounds, and compensating controls in full report. |
