Subject: [PATCH] Deny file-backed blob access when destination URL is unknown

GetAccessCallback() in FileBackedBlobFactoryBase returned a null
callback when the destination URL was invalid, even though a
ScopedFileAccessDelegate was installed. Downstream consumers treat a
null callback as "no destination known" and route to the default access
path, which is not the intended behaviour when a delegate is performing
per-destination checks.

Separate the two early-return conditions: keep returning a null callback
when no delegate is installed, but return a callback that denies access
when a delegate is installed and the destination URL is invalid (e.g.
opaque-origin workers, fenced frames). Update the comment in
FileBackedBlobFactoryFrameImpl::GetCurrentUrl() accordingly.

Original Bug Report

reported by vm...@google.com

Potential DLP bypass via fail-open invalid URLs in FileBackedBlobFactory

Project Fortify, an experimental security project, has identified the following potential security issue.

Overview: A logic error in FileBackedBlobFactoryBase causes Enterprise Data Loss Prevention (DLP) checks to fail-open when an invalid URL is encountered, such as in Fenced Frames. This allows an untrusted origin to bypass DLP policies and access restricted local files by escalating the access request to the SYSTEM component tier.

Affected files:

content/browser/blob_storage/file_backed_blob_factory_base.cc
storage/browser/file_system/local_file_stream_reader.cc
chrome/browser/chromeos/policy/dlp/dlp_scoped_file_access_delegate.cc
content/browser/blob_storage/file_backed_blob_factory_frame_impl.cc

Estimated timestamp from git blame: 2023-11-09

Summary

A potential vulnerability exists in the ChromeOS Data Loss Prevention (DLP) enforcement mechanism that could allow exfiltration of restricted files to untrusted web destinations.

When a file-backed blob is created from a context with an invalid or empty URL (specifically, a Fenced Frame), the system fails to apply restrictive policies. Instead, it defaults to a highly-privileged access level (DlpComponent::SYSTEM), bypassing Enterprise DLP rules.

Technical Details

The vulnerability stems from how the blob storage system interacts with the DLP delegate when an origin lacks a valid URL:

Invalid URL Handling in Fenced Frames: When a file-backed blob is registered via content::FileBackedBlobFactoryBase::RegisterBlobSync, it determines the destination URL for DLP checks by calling GetCurrentUrl(). For Fenced Frames, FileBackedBlobFactoryFrameImpl::GetCurrentUrl() explicitly returns an empty, invalid GURL() (see content/browser/blob_storage/file_backed_blob_factory_frame_impl.cc:34).
Null Callback Creation: RegisterBlobSync passes this empty URL to GetAccessCallback(). Because the URL is invalid (!url_for_file_access_checks.is_valid()), the helper short-circuits and returns base::NullCallback() (see content/browser/blob_storage/file_backed_blob_factory_base.cc:31). This null callback is permanently attached to the blob’s file slice.
Fail-Open during Read: When the renderer attempts to read the file (e.g., via FileReader), LocalFileStreamReader::Open is invoked. It checks for a specific file_access_ callback. Finding it null, it falls back to the default access path: file_access::ScopedFileAccessDelegate::RequestDefaultFilesAccessIO (see storage/browser/file_system/local_file_stream_reader.cc:130).
Privilege Escalation to SYSTEM: The default access path routes to DlpScopedFileAccessDelegate::RequestDefaultFilesAccess. In the default ChromeOS configuration, the strict enforcement flag kDataControlsFileAccessDefaultDeny is disabled. Consequently, the logic falls through to RequestFilesAccessForSystem, which sets the destination component to dlp::DlpComponent::SYSTEM (see chrome/browser/chromeos/policy/dlp/dlp_scoped_file_access_delegate.cc:167).
Policy Bypass: The ChromeOS DLP daemon grants access for SYSTEM destinations, allowing the untrusted Fenced Frame to read and exfiltrate admin-restricted files.

Note: Opaque-origin workers also return an empty URL in this context, but it is currently unclear if they possess the necessary web APIs (like <input type="file">) to trigger the initial RegisterBlob call for a local file path.

Potential Attack Steps

(Note: These are suggested steps; our tooling agent does not run code to verify them.)

An attacker embeds a <fencedframe> on their malicious website.
Inside the Fenced Frame, the attacker presents a file picker (<input type="file">) to the user.
The user is tricked into selecting an Enterprise DLP-protected file from their local ChromeOS file system.
The browser registers the file-backed blob, but due to the Fenced Frame context, it assigns a null DLP access callback.
The attacker’s JavaScript inside the Fenced Frame reads the file contents (e.g., using File.text()). The read succeeds because the null callback forces a fallback to SYSTEM level access, bypassing the DLP block.
The attacker exfiltrates the sensitive file data.

Recommendation

GetAccessCallback in content/browser/blob_storage/file_backed_blob_factory_base.cc should be modified. Instead of returning base::NullCallback() when a valid destination URL cannot be determined, it should return a callback that explicitly denies access or applies the most restrictive default policy.
