Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Victim must browse with a vulnerable Chrome desktop build (prior to 149.0.7827.103) to attacker-controlled HTML content that exercises the Guest View code path - typically content involving <webview>, MimeHandlerView, or other guest frame embeddings. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 reflects network-reachable, low-complexity exploitation with no privileges required but requiring user interaction (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), which is consistent with a drive-by browser bug. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts or compromises a website serving a crafted HTML page that triggers the use-after-free in Guest View, then drives traffic to it via phishing, malvertising, or watering-hole on a forum the target frequents. When a victim running a vulnerable Chrome build loads the page, the dangling pointer is dereferenced to gain code execution inside the renderer sandbox; a real-world attack chain would pair this with a separate sandbox-escape vulnerability to fully compromise the host. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 on the stable desktop channel - install immediately via Chrome's built-in updater (chrome://settings/help) or push the update through enterprise management (Group Policy, Jamf, Intune) per Google's advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all enterprise Chrome installations and identify systems running versions prior to 149.0.7827.103; prioritize executive and high-risk user devices. …
