Impact

The vulnerability resides in Chrome’s handling of CSS and enables a remote attacker to inject arbitrary scripts or HTML through a crafted webpage. Such code execution occurs within the browser context, potentially compromising user data and allowing further malicious activity. The weakness is classified under CWE‑79.

Affected Systems

Google Chrome on any platform – all releases earlier than version 151.0.7922.72 are affected.

Risk and Exploitability

The CVSS score of 6.1 indicates medium severity, while the EPSS of less than 1% suggests exploitation is currently rare but possible. The vulnerability is not listed in CISA’s KEV catalog.
