## What is CVE-2024-1483?

CVE-2024-1483 is a high-severity path traversal vulnerability in Lfprojects Mlflow, published on 16 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A path traversal vulnerability exists in mlflow/mlflow version 2.9.2, allowing attackers to access arbitrary files on the server. By crafting a series of HTTP POST requests with specially crafted 'artifact_location' and 'source' parameters, using a local URI with '#' instead of '?', an attacker can traverse the server's directory structure. The issue occurs due to insufficient validation of user-supplied input in the server's handlers.

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

Check this codebase for CVE-2024-1483 and fix it if it is affected.

What it is: CVE-2024-1483 is a high-severity path traversal vulnerability in Lfprojects Mlflow, published on 16 Apr 2024. 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-2024-1483 exists.

Affected packages and fixed versions:
- mlflow (Bitnami): affected all versions; fixed in 2.12.1
- mlflow (PyPI): affected all versions; fixed in 2.12.1
- mlflow (PyPI): affected all versions; fixed in 2.12.1

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.
