Improper initialization in Views in Google Chrome on on Windows prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sandbox escape via improper initialization (CWE-665) in Google Chrome's Views UI framework on Windows, prior to version 153.0.8010.36, can lead to arbitrary code execution outside the browser sandbox. The attack is chained: an adversary must first compromise the renderer process through a separate vulnerability, then leverage social engineering to trigger the Views initialization flaw, elevating from renderer-level code execution to full host OS access. …

Vulnerability AssessmentAI
| Exploitation | Two preconditions must hold simultaneously: (1) the attacker must have already achieved code execution inside the Chrome renderer process via a separate vulnerability - this is not a standalone flaw, it is a sandbox-escape component of a multi-stage chain; and (2) social engineering must succeed in causing the victim to interact with the crafted HTML page that triggers the Views improper initialization. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.3 vector (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) accurately captures a high-impact but genuinely complex attack path: the AC:H reflects that the adversary must already hold renderer-level code execution before this flaw is reachable, and UI:R acknowledges the social engineering requirement. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
