Insufficient policy enforcement in Downloads in Google Chrome prior to 148.0.7778.96 allowed a local attacker to bypass navigation restrictions via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Insufficient policy enforcement in Chrome's Downloads feature prior to version 148.0.7778.96 allows local attackers with user interaction to bypass navigation restrictions and access sensitive download locations via a crafted HTML page, potentially leading to information disclosure or file manipulation. The vulnerability requires local access and user engagement with a malicious page, limiting its scope to targeted social engineering rather than remote mass exploitation.
Technical ContextAI
This vulnerability affects Chrome's download policy enforcement mechanism, a security control designed to restrict where users can save downloaded files and what navigation paths are accessible during the download process. The issue resides in the Downloads subsystem of Chromium (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*), specifically in how the browser validates HTML page inputs against download destination policies. CWE classification was not provided, but the core weakness involves insufficient input validation or policy boundary enforcement when processing crafted HTML that interacts with the download handler, allowing an attacker to circumvent intended restrictions on file system navigation.
RemediationAI
Vendor-released patch: Google Chrome 148.0.7778.96 or later. Users should update to this version immediately through Chrome's automatic update mechanism or manually via Settings > About Google Chrome, which will trigger an automatic check and install. No workarounds for this vulnerability have been disclosed; the fix requires applying the patched version. The update resolves the insufficient policy enforcement in the Downloads feature, restoring navigation restriction protections. Users should verify their installed version is at least 148.0.7778.96; Chrome auto-updates to the latest stable release, but users on managed/enterprise deployments should confirm their update policies allow deployment of this patch.
