DescriptionCVE.org

Type Confusion in V8 in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome's V8 JavaScript engine prior to version 149.0.7827.53 allows attackers to execute arbitrary code within the renderer sandbox by luring a user to a malicious web page. The flaw stems from a type confusion bug rated High severity by Chromium's security team, and while no public exploit has been identified at time of analysis, V8 type confusion bugs are historically high-value targets for browser exploitation chains. A vendor patch is available.

Technical ContextAI

The vulnerability resides in V8, the open-source JavaScript and WebAssembly engine that powers Chrome and Chromium-derived browsers (Edge, Brave, Opera, Vivaldi). CWE-843 (Access of Resource Using Incompatible Type - 'Type Confusion') occurs when code allocates or accesses a resource using one type but later interprets the memory layout as a different, incompatible type. In V8, this typically arises from JIT optimization assumptions being violated (e.g., a hidden class or map check being bypassed), allowing attacker-controlled JavaScript to read or write memory outside the intended object structure. This primitive is commonly weaponized into arbitrary read/write within the renderer process, leading to arbitrary code execution inside Chrome's sandbox.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 - update Chrome via Help → About Google Chrome on all desktop endpoints and restart the browser to apply the fix, as documented in the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and the upstream issue tracker entry at https://issues.chromium.org/issues/502439789. For managed fleets, push the update via Chrome Browser Cloud Management, Group Policy, or MDM and verify deployment with version inventory. Until patching completes, compensating controls include enabling Chrome's Site Isolation (default on desktop) which limits a compromised renderer's reach, deploying browser isolation or restrictive proxy/DNS filtering to block untrusted sites (trade-off: user friction and operational overhead), and considering --js-flags=--jitless as a hardening measure for high-risk users which disables V8's JIT and removes a major attack surface but materially degrades JavaScript performance on modern web apps. Users of Chromium-based browsers (Edge, Brave, Opera, Vivaldi) should update to the version that incorporates the V8 fix as published by each vendor.
