AI Analysis

Impact

The vulnerability is an insufficient validation of untrusted input in Chrome DevTools that permits a remote attacker to construct a malicious file which, when opened by a user, forces the browser to navigate to a target URL, bypassing normal navigation restrictions. Because the flaw resides in the way DevTools interprets file content, it is classified as a combination of input validation and unsanitized input weaknesses.

Affected Systems

The affected product is Google Chrome version 151.0.7922.72 and earlier running on the stable desktop channel. This applies to all operating systems supported by Chrome: Windows, macOS, Linux, and any other platforms for which the stable channel is available.

Risk and Exploitability

The CVSS score of 6.5 indicates a medium severity, while the EPSS score of less than 1 % suggests a very low likelihood of widespread exploitation. The vulnerability is not listed in the CISA KEV catalog, and it requires a remote attacker to supply a crafted file that a user then opens in DevTools. As a result, the primary risk emanates from social engineering or phishing that prompts users to load malicious content. The overall risk is medium but limited by the user interaction prerequisite.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 151.0.7922.72 or newer to apply the vendor‑supplied fix.
  • Ensure the upgrade is deployed across all user installations, and verify that no older Chrome binaries remain in production environments.
  • Discourage users from loading unfamiliar or untrusted files into Chrome DevTools and provide training on identifying suspicious files.
