AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
Remote crafted page (AV:N, UI:R) but requires a prior renderer compromise, making it hard to chain (AC:H); the sandbox escape crosses a trust boundary (S:C) with full browser-process impact (C/I/A:H).
Primary rating from Vendor (Chrome).

Lifecycle Timeline
5DescriptionCVE.org
Object lifecycle issue in WebView in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome's Android WebView allows a remote attacker who has already compromised the renderer process to break out of the sandbox via a crafted HTML page in versions prior to 151.0.7922.72. Rooted in a use-after-free (object lifecycle) flaw rated High by Chromium, this is a second-stage privilege-boundary bypass rather than a standalone entry point. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process on Android - this is an explicit prerequisite in the CVE description and is the primary limiting factor; the flaw is a sandbox-escape primitive, not a standalone remote entry point. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed and must be read together. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first compromises the Chrome renderer process on an Android device using a separate memory-corruption bug, then lures the victim to open a crafted HTML page (satisfying the required user interaction). The page triggers the use-after-free in WebView to corrupt memory across the sandbox boundary, escalating from the constrained renderer into the higher-privileged browser process. … |
| Remediation | Vendor-released patch: update Google Chrome and Android System WebView to 151.0.7922.72 or later, which is the primary and recommended fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
