Severity by source
AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
AC:H reflects mandatory pre-compromised renderer prerequisite; S:C and C/I/A:H reflect full sandbox escape to OS scope; PR:N because the initial attacker needs no credentials.
Primary rating from Vendor (Chrome).

Improper privilege management in Navigation in Google Chrome prior to 152.0.7977.65 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 privilege management in Chrome's Navigation component allows a remote attacker who has already compromised the renderer process to break out of the Chrome sandbox and execute arbitrary code at OS level. Affected versions are all Chrome releases prior to 152.0.7977.65 across desktop platforms. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concurrent prerequisites: (1) the attacker must have already achieved code execution within the Chrome renderer process - meaning a separate renderer-level vulnerability must first be exploited - and (2) the victim must be socially engineered into a specific interaction with a crafted HTML page (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.3 (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H) captures both the severity of impact and the non-trivial prerequisites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer-level vulnerability in Chrome to gain code execution within the sandboxed renderer process, then serves a crafted HTML page that triggers the Navigation privilege mismanagement flaw while using social engineering to induce the required user interaction (such as a deceptive prompt or redirect). Once the Navigation flaw is triggered with the compromised renderer, the attacker escapes the Chrome sandbox and achieves arbitrary code execution at the OS privilege level of the Chrome process. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch for this issue. … Detailed patch versions, workarounds, and compensating controls in full report. |
