  • 388 pypi packages depend on urllib3 (299 direct, 90 indirect)

Ecosystem-wide dependent count for version 2.5.0.

DescriptionGitHub Advisory

urllib3 is a user-friendly HTTP client library for Python. 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 SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0.

Analysis

urllib3 is a user-friendly HTTP client library for Python. 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 SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain vulnerable. This issue has been patched in version 2.5.0.

Technical ContextAI

An open redirect vulnerability allows attackers to redirect users from a trusted domain to an arbitrary external URL through manipulation of redirect parameters. This vulnerability is classified as URL Redirection to Untrusted Site (Open Redirect) (CWE-601).

RemediationAI

A vendor patch is available — apply it immediately. Validate redirect URLs against a whitelist of allowed destinations. Use relative URLs for redirects. Warn users before redirecting to external sites.
