AI Analysis

Impact

An insufficient enforcement of the extension policy in Google Chrome allows a remote attacker who has already compromised the renderer process to elevate privileges through a crafted HTML page. The flaw enables the attacker to execute code bypassing intended isolation boundaries.

Affected Systems

Google Chrome versions older than 150.0.7871.47 are affected. No official workaround is presently available.

Risk and Exploitability

The CVSS score of 7.5 indicates high severity, while the EPSS score of less than 1% suggests a low likelihood of exploitation at present. The vulnerability is not listed in the CISA KEV catalog. An attacker must first achieve a renderer compromise and then serve a crafted page to further elevate privileges within the browser process.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the Google Chrome security update to version 150.0.7871.47 or later, which fixes the insufficient input validation that allowed privilege escalation.
  • Configure enterprise policies to enforce a whitelist of trusted extensions and block any extension that fails policy validation.
  • Remove or disable any untrusted or unnecessary extensions and regularly review extension permissions to ensure they adhere to the principle of least privilege.
