# Zipline: path traversal lets admins read or delete files outside uploads

Link for people: https://infrastack.ai/live/CVE-2026-126944 (this .md is for agents)

Zipline before 4.6.1 has a path traversal flaw in its LocalDatasource that lets a SUPERADMIN user import records with traversal filenames. An attacker can read or delete files the Zipline process can access outside the upload directory.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Zipline version in use; affected versions are those before `4.6.1`.
- Confirm whether the instance uses local storage (LocalDatasource) for uploads.

## Fix

- Zipline: move to `4.6.1` or later.

## From the sources

Zipline before 4.6.1 contains a path traversal vulnerability in LocalDatasource that allows SUPERADMIN users to read or delete files outside the upload directory by importing records with traversal filenames. Attackers can trigger the unchecked range-read path with byte-range requests or set expired deletion times to delete files accessible to the Zipline process.
