## What is CVE-2024-12217?

CVE-2024-12217 is a medium-severity path traversal vulnerability in gradio-app/gradio, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A 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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

What it is: CVE-2024-12217 is a medium-severity path traversal vulnerability in gradio-app/gradio, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-12217 exists.

Affected packages and fixed versions:
- gradio (PyPI): affected all versions up to 5.0.1; no fix listed
- gradio (PyPI): affected all versions up to 5.0.1; no fix listed
- gradio (PyPI): affected all versions up to 5.0.1; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
