AI Analysis
Technical Summary
CVE-2026-91728 is an integer overflow vulnerability in the V8 engine of Google Chrome before version 153.0.8010.47. Exploitation involves a remote attacker crafting a malicious HTML page that triggers the overflow, enabling arbitrary code execution inside the sandbox environment. The vulnerability is classified under CWE-190 (Integer Overflow or Wraparound) and has a CVSS v3.1 base score of 9.6, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code within the sandboxed environment of the browser, potentially compromising the confidentiality, integrity, and availability of the affected system. This could lead to unauthorized actions or data exposure within the browser context.
Mitigation Recommendations
A fix is available in Google Chrome version 153.0.8010.47. Users and administrators should update to this version or later to remediate the vulnerability. Since this is a client-side application, patching the browser is the primary mitigation step.
