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 V8 JavaScript engine prior to version 149.0.7827.53 allows a remote attacker to execute arbitrary code inside the renderer sandbox by serving a crafted HTML page to a victim. The flaw is a type confusion bug (CWE-843) in V8 rated High severity by Chromium, with no public exploit identified at time of analysis and SSVC indicating exploitation status 'none' from CISA's framework.
Technical ContextAI
V8 is the open-source JavaScript and WebAssembly engine that powers Chrome, Edge, Opera, and other Chromium-derived browsers, as well as Node.js. CWE-843 (Type Confusion) occurs when code allocates or accesses a resource using one type but later interprets it as an incompatible type, which in a JIT-compiling engine like V8 typically leads to memory corruption because object layouts and inline-cache assumptions diverge from reality. Affected CPE coverage per ENISA EUVD is Chrome builds below 149.0.7827.53; while Chrome itself is the named product, downstream Chromium-based browsers and any Electron/CEF applications embedding the same V8 build are likely impacted until they rebase.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 - upgrade Chrome Stable to this version or later via the built-in updater (Help > About Google Chrome) and restart the browser to load the patched V8, per https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Enterprises managing Chrome via policy should force-push the update and confirm with chrome://version on endpoints; downstream Chromium browsers should be updated as soon as their vendors ship a rebased build. As a temporary compensating control where patching is delayed, restrict browsing to trusted sites via enterprise URL allowlists, enable Site Isolation (default on desktop) to keep the renderer compromise contained, and consider disabling JIT in V8 via the --js-flags='--jitless' command-line switch or the JavaScriptJitlessIsAllowed enterprise policy where supported - note this materially degrades JavaScript performance and may break complex web apps.
