AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Remote crafted page needs only a victim visit (UI:R, PR:N, AC:L); sandbox escape justifies scope change (S:C) with full C/I/A on the host.

Use after free in Aura in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox-escaping remote code execution in Google Chrome (desktop, versions before 152.0.7977.65) stems from a use-after-free in Aura, Chromium's UI/windowing framework. A remote attacker who lures a victim to a crafted HTML page can execute arbitrary code outside the browser sandbox, giving full control of the host process rather than just the renderer. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load attacker-controlled HTML in a vulnerable Chrome build (before 152.0.7977.65) - the CVSS UI:R and the description's 'crafted HTML page' confirm user interaction (visiting/rendering a page) is the trigger. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed but lean toward high-priority patching. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page (or injects it via a malicious ad or compromised site) that triggers the Aura use-after-free when rendered. A victim simply visiting the page allows the attacker to corrupt freed memory and execute code outside the Chrome sandbox, gaining control of the host with the user's privileges. … |
| Remediation | Vendor-released patch: update Google Chrome to 152.0.7977.65 or later on all desktop platforms; the fix is delivered through the Stable channel update described in the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all systems running Chrome versions before 152.0.7977.65, and notify endpoint teams of the patching requirement. …
