CVE-2025-50181
MEDIUM5.3EPSS 0.08%urllib3 redirects are not disabled when retries are disabled on PoolManager instantiation
發布日:2025/6/18修改日:2026/4/28
描述
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.
