Insufficient policy enforcement in Speech in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
AI Analysis
Technical Summary
CVE-2026-18004 describes an insufficient policy enforcement vulnerability in the Speech feature of Google Chrome versions before 151.0.7922.72. This flaw enables a remote attacker, who already controls the renderer process, to exfiltrate cross-origin data by leveraging a specially crafted HTML page. The vulnerability does not have an assigned CVSS score but is classified by Chromium as low severity.
Potential Impact
An attacker with control over the renderer process can exploit this vulnerability to leak data from different origins, potentially violating same-origin policy protections. This could lead to unauthorized disclosure of sensitive information accessible within the browser context. However, the impact is limited by the prerequisite that the attacker must have already compromised the renderer process.
Mitigation Recommendations
A fix is available in Google Chrome version 151.0.7922.72 and later. Users and administrators should update to this version or a later release to remediate the vulnerability. No additional mitigations are specified.
