Google Chrome Vulnerability CVE-2026-87491 Allows Remote Code Execution

## Overview A high-severity vulnerability, CVE-2026-87491, has been identified in Google Chrome. This flaw exists in the V8 JavaScript engine, which is part of Chrome's core functionality. It allows remote attackers to execute arbitrary code within the browser's sandbox environment via a specially crafted HTML page. ## Technical Details The vulnerability is categorized as an out-of-bounds write. This occurs when the application writes data outside the allocated memory bounds. Such flaws can lead to memory corruption, enabling attackers to manipulate the execution flow of the application. In this case, it affects versions of Google Chrome prior to 153.0.8010.36. The issue was reported and classified with a CVSS score of 8.8, indicating a high level of severity. ## Impact Successful exploitation of CVE-2026-87491 allows attackers to execute arbitrary code in the context of the user. This could lead to unauthorized access to sensitive information or further compromise of the system. The sandbox environment typically limits the impact of such attacks, but vulnerabilities like this can bypass those protections under certain conditions. ## Mitigation Defenders should prioritize updating Google Chrome to version 153.0.8010.36 or later. Users should enable automatic updates or manually check for updates to ensure they are protected against this vulnerability. Additionally, organizations should consider implementing web filtering solutions to block access to potentially malicious sites that could exploit this flaw.
