## What is CVE-2024-12216?

CVE-2024-12216 is a high-severity path traversal vulnerability in dmlc/gluon-cv, published on 20 Mar 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A vulnerability in the `ImageClassificationDataset.from_csv()` API of the `dmlc/gluon-cv` repository, version 0.10.0, allows for arbitrary file write. The function downloads and extracts `tar.gz` files from URLs without proper sanitization, making it susceptible to a TarSlip vulnerability. Attackers can exploit this by crafting malicious tar files that, when extracted, can overwrite files on the victim's system via path traversal or faked symlinks.

Weakness: CWE-59 (Improper Link Resolution Before File Access)

What it is: CVE-2024-12216 is a high-severity path traversal vulnerability in dmlc/gluon-cv, published on 20 Mar 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-12216 exists.

Affected packages and fixed versions:
- gluoncv (PyPI): affected all versions up to 0.10.0; no fix listed
- gluoncv (PyPI): affected all versions up to 0.10.0; no fix listed
- gluoncv (PyPI): affected all versions up to 0.10.0; 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.
