Analysis

AI-generated

Technical impact

In Google Chrome versions prior to 149.0.7827.53, an inappropriate implementation within the Dawn graphics engine lets a malicious actor who has already compromised the renderer process run arbitrary code inside the browser’s sandboxed environment. The flaw allows exploitation through a specially crafted HTML page, giving attackers the ability to execute code with the renderer’s privileges.

Affected Systems

Vendors affected are Google Chrome. Any client running Chrome below version 149.0.7827.53 is vulnerable. Versions 149.0.7827.53 and later include the fix.

Risk and Exploitability

The EPSS score is 0.00106, indicating a very low exploitation probability, and the vulnerability is not listed in CISA’s KEV catalog. The attack vector requires an initial compromise of the renderer, after which a crafted HTML page can trigger the flaw. Given a CVSS score of 8.8, the risk is high for users who may visit untrusted web content. No publicly known active exploits are documented at this time.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Chrome to version 149.0.7827.53 or later.
  • Enable policies or extensions that restrict renderer privileges and prevent untrusted HTML content from loading.
  • Educate users to avoid clicking on suspicious links or downloading untrusted files that could contain malicious HTML.
