Policy bypass in Downloads in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to bypass of multi-download protections via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Google Chrome versions prior to 147.0.7727.55 contain a policy bypass vulnerability in the Downloads feature that allows remote attackers to circumvent multi-download protections through a crafted HTML page. The vulnerability requires user interaction (clicking or accepting a download), affects integrity only (no code execution or availability impact), and carries a low Chromium severity rating. EPSS exploitation probability is minimal at 0.02% (3rd percentile), indicating this is primarily a user-experience or policy-enforcement issue rather than a critical security risk.

Technical ContextAI

This vulnerability exists in Chrome's Downloads component security policy enforcement mechanism, classified under CWE-693 (Protection Mechanism Failure). The issue involves improper validation or enforcement of multi-download protection policies-features designed to prevent rapid or bulk malicious downloads. The vulnerability does not affect the core security architecture of Chromium's sandboxing, process isolation, or content security policy implementation; rather, it represents a gap in higher-level user-facing protection controls that warn or block suspicious download patterns. The CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* indicates all Chrome variants across platforms are affected until the patched version.

RemediationAI

Update Google Chrome to version 147.0.7727.55 or later immediately. Users on Windows, macOS, and Linux can trigger updates via Chrome Menu > Help > About Google Chrome, which will automatically download and install the latest version (requiring a browser restart). Enterprise administrators should use Google Chrome for Business or Chrome Enterprise to centrally manage updates via policy. No workarounds are available, but the low EPSS score indicates this is not an urgent zero-day requiring emergency patching-standard update schedules suffice.
