AI Analysis

Impact

In Chrome releases before 151.0.7922.72, the Passwords component improperly validates untrusted input, allowing a malicious renderer process to escape the browser sandbox. This vulnerability can enable an attacker to execute arbitrary code and compromise the host system, representing a significant integrity and confidentiality breach. The flaw is categorized as CWE‑1289.

Affected Systems

Google Chrome browsers on all platforms with versions prior to 151.0.7922.72 are affected.

Risk and Exploitability

The CVSS score of 9.6 indicates high severity, while the EPSS score of less than 1% suggests low current exploitation likelihood. The vulnerability is not listed in the CISA KEV catalog. It can be exploited through a crafted HTML page that targets the vulnerable Passwords function, and requires compromise of the renderer process, making it a remote attack vector that can lead to full system compromise if successful.
