Analysis

Impact

A flaw in the Glic component of Google Chrome allows a remote attacker to escape the browser sandbox because the component insufficiently validates untrusted HTML input (CWE‑20). When exploited, this vulnerability could elevate the attacker’s privileges beyond the sandbox, enabling the execution of arbitrary code on the host system and threatening confidentiality, integrity, and availability.

Affected Systems

Google Chrome installations on any desktop operating system that are running a version older than 150.0.7871.47 are affected; the vulnerability applies to all desktop environments where a vulnerable Chrome instance is used.

Risk and Exploitability

The CVSS score of 8.8 signals a high‑severity flaw, meaning substantial impact if the weakness is triggered. The EPSS score of less than 1% suggests that exploitation attempts are rare. The vulnerability is not cataloged in CISA KEV. The likely attack vector is a remote attacker delivering a crafted HTML page or file that the browser processes, which may allow the attacker to escape the sandbox.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Upgrade Google Chrome to version 150.0.7871.47 or later to apply the vendor patch that adds proper input validation for Glic.
Enable Chrome’s Safe Browsing and configure the browser to refuse opening local or network HTML files that are not served over HTTPS, thereby enforcing strict validation of untrusted content (mitigating the CWE‑20 weakness).
Keep your operating system, security software, and Chrome extensions up to date, and avoid installing extensions that allow the browser to access or render arbitrary local files.
