URL Redirection to Untrusted Site ('Open Redirect')

CVE-2025-50181

Medium
5.3/10

Summary

The package urllib3 is a user-friendly HTTP client library for Python. In versions prior to 2.5.0, it is possible to disable redirects for all requests by instantiating a `PoolManager` and specifying `retries` in a way that disable redirects. By default, requests and botocore users are not affected. An application attempting to mitigate Server-Side Request Forgery (SSRF) or Open Redirect vulnerabilities by disabling redirects at the `PoolManager` level will remain vulnerable.
