## What is CVE-2025-48889?

CVE-2025-48889 is a medium-severity path traversal vulnerability in Gradio Project Gradio, published on 30 May 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Gradio is an open-source Python package that allows quick building of demos and web application for machine learning models, API, or any arbitrary Python function. Prior to version 5.31.0, an arbitrary file copy vulnerability in Gradio's flagging feature allows unauthenticated attackers to copy any readable file from the server's filesystem. While attackers can't read these copied files, they can cause DoS by copying large files (like /dev/urandom) to fill disk space. This issue has been patched in version 5.31.0.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)

Affected packages and fixed versions:
- gradio (PyPI): affected all versions; fixed in 5.31.0
- gradio (PyPI): affected all versions; fixed in 5.31.0
- gradio (PyPI): affected from 5.25.2; fixed in 5.31.0

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.
