AI Analysis

Impact

Improper privilege management in the navigation component of Google Chrome prior to version 152.0.7977.65 allows a remote attacker who has already compromised the renderer process to use a crafted HTML page and social engineering techniques to execute code outside the browser sandbox. The flaw is a classic example of improper privilege management (CWE‑269) and can lead to arbitrary code execution with the privileges of the renderer process or even higher if the sandbox is bypassed.

Affected Systems

Google Chrome versions earlier than 152.0.7977.65 are affected. Any installation of Google Chrome that has not yet been updated to the 152.0.7977.65 release contains the vulnerable navigation logic and can be exposed to a malicious webpage.

Risk and Exploitability

According to Chromium, the vulnerability carries a CVSS score of 8.3. The EPSS score of < 1% indicates the exploitation probability is low, and the flaw is not listed in the CISA KEV catalog. The absence of a publicly known exploit and the CVSS score of 8.3 suggest that the overall risk is high, but the potential impact of sandbox escape warrants prompt action.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade to Chrome version 152.0.7977.65 or later, which contains the fixed navigation logic.
  • Verify that the operating system and Chrome's sandboxing features are enabled and have not been disabled by third‑party software or policy settings.
  • Continuously monitor Google's release notes and security advisories for further updates or related vulnerabilities.
