CVE-2026-14045 - Vulnerability Details

Description

Insufficient validation of untrusted input in Network in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)

Analysis

Impact

The vulnerability results from insufficient validation of untrusted input in Chrome’s Network component. When a renderer process is compromised, a maliciously crafted HTML page can cause the browser to disclose and transmit private data from other origins, enabling cross‑origin data leakage without escalating privileges.

Affected Systems

The issue affects Google Chrome releases before version 150.0.7871.47. A stable‑channel update was issued in June 2026 to fix the problem, so users on older releases remain at risk of leaking data from other origins.

Risk and Exploitability

The CVSS base score of 4.3 indicates low severity, and the EPSS score of less than 1 % plus absence from the CISA KEV catalog suggest limited real‑world exploitation. Exposition requires an attacker to already compromise the renderer process, typical deployments. The CWE‑20, improper input validation.

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.
Ensure the renderer process runs with the strictest sandbox settings available to reduce the impact of a compromised renderer.
Configure a content security policy that limits cross‑origin resource sharing so leaked data cannot be exfiltrated to malicious domains.
