19 Jun 2025 — urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, urllib3 does not control redirects in browsers and Node.js. urllib3 supports being used in a Pyodide runtime utilizing the JavaScript Fetch API or falling back on XMLHttpRequest. This means Python libraries can be used to make HTTP requests from a browser or Node.js. Additionally, urllib3 provides a mechanism to control redirects, but the retries and redirect parameters are ignored with Pyodide; the runtime itself determines redirect... • https://github.com/urllib3/urllib3/commit/7eb4a2aafe49a279c29b6d1f0ed0f42e9736194f • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2025-50181 – urllib3 redirects are not disabled when retries are disabled on PoolManager instantiation
https://notcve.org/view.php?id=CVE-2025-50181
19 Jun 2025 — 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. • https://github.com/urllib3/urllib3/commit/f05b1329126d5be6de501f9d1e3e36738bc08857 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 4.6EPSS: 0%CPEs: 2EXPL: 0CVE-2024-37891 – Proxy-Authorization request header isn't stripped during cross-origin redirects in urllib3
https://notcve.org/view.php?id=CVE-2024-37891
17 Jun 2024 — urllib3 is a user-friendly HTTP client library for Python. When using urllib3's proxy support with `ProxyManager`, the `Proxy-Authorization` header is only sent to the configured proxy, as expected. However, when sending HTTP requests *without* using urllib3's proxy support, it's possible to accidentally configure the `Proxy-Authorization` header even though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn't treat the `Proxy-Authoriz... • https://github.com/urllib3/urllib3/commit/accff72ecc2f6cf5a76d9570198a93ac7c90270e • CWE-669: Incorrect Resource Transfer Between Spheres •

https://notcve.org/view.php?id=CVE-2023-45803
17 Oct 2023 — urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs. Although this behavior is not specified in the section for redirects, it can be inferred by piecing together information from different sections and we have observed the behavior in other major HTTP c... • https://github.com/urllib3/urllib3/commit/4e98d57809dacab1cbe625fddeec1a290c478ea9 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2023-43804
04 Oct 2023 — urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. urllib3 es una librería cliente HTTP fácil de usa... • https://github.com/JawadPy/CVE-2023-43804-Exploit • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
