CVE-2026-5871: Type Confusion in Google Chrome
Type Confusion in V8 in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability involves a type confusion bug in the V8 engine of Google Chrome before version 147.0.7727.55. An attacker can exploit this by delivering a specially crafted HTML page that triggers arbitrary code execution inside the sandboxed environment of the browser. The vulnerability is remotely exploitable without privileges and requires user interaction (visiting a malicious page). The CVSS vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code within the sandbox of the affected Chrome browser, potentially compromising the confidentiality, integrity, and availability of the user's browsing environment. This could lead to unauthorized actions within the browser context, but the sandbox limits impact to the browser process.
Mitigation Recommendations
Google has released an official fix in Chrome version 147.0.7727.55. Users and administrators should update affected Chrome installations to this version or later to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
