AI Analysis
Technical Summary
This vulnerability in Google Chrome (CVE-2026-18004) arises from insufficient policy enforcement in the Speech component. An attacker with control over the renderer process can exploit this flaw to leak cross-origin data by crafting a malicious HTML page. The issue affects versions before 151.0.7922.72. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and limited confidentiality impact. The vulnerability is classified under CWE-284 (Improper Access Control).
Potential Impact
An attacker who has already compromised the renderer process can leak cross-origin data, potentially exposing sensitive information from other origins. The impact is limited to confidentiality with no integrity or availability impact. The overall severity is medium.
