Inappropriate implementation in PDF in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Google Chrome prior to version 147.0.7727.55 contains an inappropriate PDF implementation that allows remote attackers to bypass navigation restrictions via a crafted HTML page. The vulnerability requires user interaction to trigger and offers low real-world risk, with an EPSS score of 0.02% (3rd percentile) indicating minimal exploitation probability despite its network-accessible attack vector. A vendor-released patch is available.
Technical ContextAI
The vulnerability resides in Google Chrome's PDF handling implementation (CWE-358: Inappropriate Implementation), where navigation restriction controls are insufficiently enforced when processing specially crafted HTML pages that interact with PDF content. The affected component is part of Chrome's core PDF rendering engine. The vulnerability is specific to the PDF-in-Chrome feature and does not affect the underlying PDF specification itself, but rather how Chrome applies navigation policies to PDF documents loaded from or referenced by web pages. The issue allows circumvention of intended security boundaries that prevent PDF documents from performing certain navigation actions.
RemediationAI
Vendor-released patch: Update Google Chrome to version 147.0.7727.55 or later. Most users will receive this update automatically through Chrome's built-in auto-update mechanism; no manual intervention is typically required. Verify the installed version via Chrome menu (three dots) → Help → About Google Chrome, which will display the current version and trigger any pending updates. Organizations managing Chrome enterprise deployments should consult Google's official advisory at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop.html for deployment guidance. No workarounds are documented for versions prior to the patch.
