A high-severity use-after-free vulnerability in Google Chrome's Read Anything component poses a significant risk of sandbox escape to remote attackers.

This is a use-after-free vulnerability occurring within the Read Anything feature. It requires an attacker to successfully compromise the renderer process, at which point they may leverage this flaw to perform a sandbox escape using a specially crafted HTML page.

The vulnerability carries a CVSS score of 8.3, indicating a high risk to organizational security. Successful exploitation could allow an attacker to break out of the browser's security sandbox, potentially leading to unauthorized access to the underlying operating system, data exfiltration, or further lateral movement within the network.

Immediate Action: Update all instances of Google Chrome to version 149.0.7827.103 or later immediately.

Proactive Monitoring: Monitor browser-related process logs for unexpected crashes or anomalous behavior that may indicate an exploitation attempt.

Compensating Controls: Ensure that endpoint protection solutions are active and that browsers are running with standard security policies enabled to limit the impact of potential sandbox escapes.

Public Exploit Available: false

Given the severity of sandbox escape vulnerabilities, administrators must prioritize the deployment of the 149.0.7827.103 update across all managed endpoints. Failure to patch allows for a critical security gap that could be weaponized by remote actors to bypass core browser protections.
