CVE-2024-12217
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability in the gradio-app/gradio repository, version git 67e4044, allows for path traversal on Windows OS. The implementation of the blocked_path functionality, which is intended to disallow users from reading certain files, is flawed. Specifically, while the application correctly blocks access to paths like 'C:/tmp/secret.txt', it fails to block access when using NTFS Alternate Data Streams (ADS) syntax, such as 'C:/tmp/secret.txt::$DATA'. This flaw can lead to unauthorized reading of blocked file paths.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA path traversal vulnerability in Gradio's blocked_path functionality on Windows allows bypassing file access restrictions via NTFS Alternate Data Streams (ADS) syntax. While normal paths like 'C:/tmp/secret.txt' are correctly blocked, paths using ADS notation such as 'C:/tmp/secret.txt::$DATA' are not blocked, enabling unauthorized file reads.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if Gradio is installedRun 'pip show gradio' or 'pip list | grep gradio' to see installed versionAffected if Gradio is installed and version is any release (no fixed version range provided)
-
Verify Windows operating systemRun 'systeminfo' or 'echo %OS%' or check 'platform.system()' in Python - the vulnerability only affects WindowsAffected if Running on Windows; Linux/macOS are not affected by this specific NTFS ADS bypass
-
Confirm blocked_path is in useSearch Gradio application code for usage of 'blocked_path' parameter or function; check Gradio configuration files for path restrictionsAffected if blocked_path functionality is configured and actively blocking file paths in the application
-
Test ADS syntax bypass manuallyAttempt to access a known-blocked file using ADS syntax (e.g., if 'C:/tmp/secret.txt' is blocked, try accessing 'C:/tmp/secret.txt::$DATA' through Gradio's file serving endpoint)Affected if The ADS syntax path returns file contents while the normal path is correctly blocked - this indicates the vulnerability is present
A user is affected if they run Gradio on Windows with blocked_path configured and the ADS syntax (::$DATA) can bypass the block to read restricted files.
