CVE-2026-87594: Incorrect authorization in Google Chrome
Incorrect authorization in DataTransfer in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
CVE-2026-87594 is an authorization bypass vulnerability in the DataTransfer feature of Google Chrome versions before 153.0.8010.36. This flaw allows a remote attacker, who has already compromised the renderer process, to access sensitive information by leveraging crafted HTML content. The issue relates to improper enforcement of authorization checks (CWE-863). No detailed exploit techniques or impact beyond information disclosure are described in the available data.
Potential Impact
A remote attacker with control over the renderer process can bypass authorization checks in DataTransfer to access sensitive information. This could lead to information disclosure within the browser context. There is no indication of privilege escalation beyond the renderer compromise or broader system impact.
Mitigation Recommendations
A fix is available in Google Chrome version 153.0.8010.36. Users and administrators should update to this version or later to remediate the vulnerability. Since this is a client software vulnerability, patching the browser is the recommended mitigation.
