Inappropriate implementation 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)
AnalysisAI
Remote code execution in Google Chrome versions prior to 147.0.7727.55 allows unauthenticated attackers to execute arbitrary code within the browser's sandbox through a crafted HTML page exploiting an inappropriate implementation in the V8 JavaScript engine. User interaction is required (visiting a malicious webpage). No public exploit identified at time of analysis, with EPSS exploitation probability at 0.04% (11th percentile), indicating low observed attacker interest despite high CVSS severity.
Technical ContextAI
This vulnerability affects Google Chrome's V8 JavaScript engine, which compiles and executes JavaScript code in Chrome and Chromium-based browsers. An 'inappropriate implementation' represents a flaw in how V8 handles certain JavaScript operations or memory management during compilation or runtime execution. The CPE string (cpe:2.3:a:google:chrome) confirms all Chrome versions below 147.0.7727.55 are affected. While execution occurs within Chrome's sandbox architecture (limiting system-level impact), sandbox escape vulnerabilities are often chained with such flaws to achieve full system compromise. The lack of assigned CWE suggests the root cause may involve multiple weakness classes or represents a novel implementation flaw specific to V8's architecture.
RemediationAI
Vendor-released patch: Update Google Chrome to version 147.0.7727.55 or later immediately through Chrome's built-in update mechanism (Settings > About Chrome) or by downloading the latest version from google.com/chrome. Chrome typically auto-updates within 24-48 hours for most users, but manual verification is recommended for enterprise environments. For organizations managing Chrome via Group Policy or MDM solutions, push version 147.0.7727.55 through your standard deployment channels. No effective workarounds exist short of disabling JavaScript entirely (which breaks modern web functionality). Organizations unable to patch immediately should implement defense-in-depth controls including restricting access to untrusted websites via web filtering, deploying browser isolation technologies for high-risk browsing, and ensuring endpoint detection solutions monitor for suspicious browser process behavior.
