CVE-2026-13990 - Vulnerability Details

Description

Insufficient validation of untrusted input in DataTransfer in Google Chrome on Windows prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)

Analysis

Impact

The vulnerability is an input validation flaw in Google Chrome on Windows that allows a remote attacker who has already compromised the renderer process to deliver crafted HTML. The attacker can exploit insufficient sanitization of DataTransfer data to cause the browser to render deceptive user interface elements, potentially luring users into unintended actions.

Affected Systems

Google Chrome for Windows is affected. All versions prior to 150.0.7871.47 contain the flaw. The fixed releases, beginning with 150.0.7871.47, validate DataTransfer input correctly.

Risk and Exploitability

The flaw receives a CVSS score of 6.5, indicating medium severity. The EPSS score of <1% suggests a low likelihood of exploitation at present. It is not listed in CISA’s KEV catalog, indicating no known widespread exploitation. Exploitation requires an attacker first to compromise the renderer process; after that, supplied crafted HTML can bypass validation and perform UI spoofing. The risk is bounded to the scope of the renderer and the integrity of the browser’s UI.

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