Inappropriate implementation in PlatformIntegration in Google Chrome on Windows prior to 149.0.7827.53 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code via a malicious file. (Chromium security severity: Low)
AnalysisAI
Remote code execution in Google Chrome on Windows prior to version 149.0.7827.53 allows a remote attacker to run arbitrary code when a victim is lured into performing specific UI gestures involving a malicious file delivered through the PlatformIntegration component. The flaw stems from improper input validation (CWE-20) and, while a vendor patch is available, no public exploit has been identified at time of analysis and EPSS scoring (0.04%) indicates very low near-term exploitation probability.
Technical ContextAI
The vulnerability resides in Chrome's PlatformIntegration subsystem, the component that mediates interactions between the Chromium browser process and host operating system features on Windows (file handling, OS shell integration, drag-and-drop, and similar bridging functionality). The root cause is classified as CWE-20 (Improper Input Validation), meaning a malicious file or its associated metadata is not properly validated before being acted upon by Windows-specific platform code. Chromium internally rated the issue as Low severity, suggesting the practical attack surface is constrained by the required UI interaction, even though the cross-process consequences can yield arbitrary code execution.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 for Windows - upgrade immediately via Chrome's auto-update channel or enterprise deployment tooling, then restart the browser to apply (see https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html). Enterprises managing Chrome via group policy should validate that the AutoUpdate and ComponentUpdate policies are not disabled, since pinned older builds will remain exposed. As compensating controls until patching completes, restrict download of untrusted file types via SmartScreen and Windows Attachment Manager policies, enforce 'Open file' warnings, and consider enabling Microsoft Defender Application Guard or Chrome Enterprise Connectors safe-browsing enhanced protection - trade-off is added user friction on legitimate downloads. Avoid blocking PlatformIntegration broadly as it would degrade core browser/OS interoperability (drag-and-drop, file open).
