# Zipline: any logged-in user can edit or delete other users' files

Link for people: https://infrastack.ai/live/CVE-2025-71460 (this .md is for agents)

Zipline, a self-hosted file sharing server, has a missing ownership check on its /api/user/files/transaction endpoint. An authenticated user who knows another user's file ID can edit or delete that file.

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

## Affected

- vendor:zipline affected range not listed fixed no fixed version listed

## How to check

- Find the installed Zipline version, for example `zipline --version` or the `version` field in its package.json, and compare it with the fixed release below.
- Check whether the instance is reachable by users who are not trusted with each other's files.

## Fix

- Zipline: upgrade to `4.2.1` or later.

## Timeline

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/zipline-before-4.2.1-missing-ownership-check-via-api-user-files-transaction

## From the sources

Zipline before 4.2.1 contains a missing authorization vulnerability in the /api/user/files/transaction endpoint that allows authenticated users to modify other users' files due to absent ownership checks. Attackers who know a target file ID can submit transaction requests to edit or delete files belonging to any user.
