urllib3-future is vulnerable to URL Redirection to Untrusted Site ('Open Redirect')

Medium Risk
This Affects:
urllib3-futureTL;DR
Affected versions of this package are vulnerable to an open redirect, addressed via a backported security fix (CVE-2025-50181) from urllib3 v2.5.0. The urllib3-future package is designed for use in Pyodide environments, enabling Python HTTP requests through the JavaScript Fetch API or XMLHttpRequest. Although it offers redirect control via retries and redirect parameters, these are ineffective in Pyodide, where the runtime governs redirect behavior—potentially allowing malicious redirects if not properly handled.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
