# Zipline: login page XSS via unvalidated url parameter

Link for people: https://infrastack.ai/live/CVE-2025-71462 (this .md is for agents)

Zipline, a self-hosted file sharing server, fails to validate the url parameter on its login page. An attacker can craft a login link with a javascript: URI that runs script in the victim's browser after they log in.

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

## How to check

- Check the Zipline version in your deployment, for example in `package.json` or the container image tag.
- Look for the login page's `url` parameter handling in your deployed build if you have modified it.

## Fix

- Zipline `3.7.12` (fixes all versions before `3.7.12`).

## Documents

- [advisory] Vendor advisory: github.com https://github.com/diced/zipline/security/advisories/GHSA-m288-p6wr-m6gv
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/zipline-before-3.7.12-xss-via-url-parameter-on-login-page

## From the sources

Zipline before 3.7.12 contains a cross-site scripting vulnerability in the login page that allows attackers to execute JavaScript by supplying an unvalidated url parameter. Attackers can craft a login link with a javascript: URI in the url parameter that executes in the victim's browser after login.
