CVE-2026-11107

chromium-browser: Inappropriate implementation in Downloads

Published Jun 4, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

Inappropriate implementation in Downloads in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)

Analysis

Technical impact

The vulnerability exists in Chrome’s download handling logic and allows a remote attacker to load a specially crafted HTML page that can spoof the browser’s user interface. By masquerading as a legitimate site or function, the attacker can deceive the user into interacting with malicious content. The Chromium security severity is listed as Medium, indicating a notable risk to user trust and interaction but no direct evidence of code execution or system compromise. The flaw aligns with CWE-1021 and CWE-451 vulnerabilities.

Affected Systems

Google Chrome versions prior to 149.0.7827.53 on all supported operating systems are affected. The issue is tied to the Downloads component of the browser.

Risk and Exploitability

The EPSS score is < 1% and the vulnerability is not listed in the CISA KEV catalog. The CVSS score of 4.3 indicates a Medium severity. The likely attack vector is remote, with the attacker delivering a crafted HTML page via a web link or possibly email. No additional prerequisites such as local privileges are required, and exploitation can occur in the normal browsing mode.

Affected Products

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

OpenCVE Recommended Actions

Apply the Chrome update to version 149.0.7827.53 or later, immediately fixing the download handling flaw that enables UI spoofing.
Configure Chrome to isolate download pages in a sandboxed environment and enforce strict sanitization of any HTML content, which mitigates the UI spoofing (CWE‑451) and input validation (CWE‑1021) weaknesses.
Enable Chrome’s Safe Browsing and Content Security Policy features to detect and block malicious HTML rendering, protecting against potential cross‑site scripting.
