DescriptionCVE.org

Inappropriate implementation 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 a remote attacker to execute arbitrary code within the browser sandbox by luring a user to a crafted HTML page. Rated High severity by Chromium with a CVSS 8.8, the flaw requires user interaction (visiting a malicious site) but no authentication or privileges. No public exploit has been identified at the time of analysis, and the issue is not currently listed in CISA KEV.

Technical ContextAI

The vulnerability resides in V8, the open-source JavaScript and WebAssembly engine that powers Chrome and Chromium-derived browsers (Edge, Opera, Brave, Electron apps). It is classified under CWE-20 (Improper Input Validation), described by Google as an 'inappropriate implementation' bug - typically a logic flaw in the engine's handling of language semantics, optimizations, or runtime checks rather than a classic memory-corruption issue. Successful exploitation yields arbitrary code execution constrained to Chrome's renderer sandbox, meaning a second sandbox-escape bug would be needed to fully compromise the host.

RemediationAI

Vendor-released patch: update Google Chrome to 149.0.7827.53 or later via the stable-channel update referenced at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html; in managed environments, push the update through enterprise channels (Chrome Browser Cloud Management, MSI/MDM, or auto-update policies) and confirm with chrome://settings/help. Track upstream Chromium issue https://issues.chromium.org/issues/506855825 for technical detail once unrestricted. For Chromium derivatives, apply the vendor's corresponding update (Edge, Brave, Opera, etc.) and rebuild any Electron/CEF applications against a patched runtime. If immediate patching is not possible, compensating controls include disabling JavaScript on untrusted origins via enterprise policy (DefaultJavaScriptSetting=2 with allowlists - breaks most modern web apps), enforcing Site Isolation and the strictest sandboxing flags (already default but verify), and using web filtering or DNS controls to block known malicious domains; these are partial mitigations only and degrade browsing functionality.
