AI Analysis

Impact

An insufficient policy enforcement flaw in Google's Chrome Media component on Windows allows a remote attacker to bypass the browser's site isolation boundary by serving a specially crafted HTML page. This improper access control issue (CWE-602) lets the attacker read or modify data that is normally confined to a separate process, undermining cross-site confidentiality and integrity.

Affected Systems

All Windows installations of Google Chrome running a version earlier than 150.0.7871.47 are affected. Based on the description, it appears that no equivalent problem is documented for macOS or Linux distributions.

Risk and Exploitability

The CVSS score is 6.5, indicating moderate severity, while the EPSS score of <1% shows a very low probability of widespread exploitation. Although the vulnerability is not listed in CISA's KEV, the breach of site isolation could grant an attacker unauthorized access to multiple sites and browser processes. The likely attack vector is remote: the attacker delivers a malicious HTML page that triggers a user to visit a crafted web page.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 150.0.7871.47 or later to eliminate the improper access control flaw (CWE-602).
  • Apply an organization-wide Chrome policy that blocks or tightly restricts automatic loading of external media content, thereby limiting the window for the flaw to be abused.
  • Configure a strict Content Security Policy that disallows mixed content, mitigating potential exploitation paths.
