[Security] Bump urllib3 from 2.0.7 to 2.2.2

Ronan Amicelrequested to merge
dependabot-pip-urllib3-2.2.2 into main

Bumps urllib3 from 2.0.7 to 2.2.2. This update includes a security fix.

Vulnerabilities fixed

urllib3's Proxy-Authorization request header isn't stripped during cross-origin redirects 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-Authorization HTTP header as one carrying authentication material and thus doesn't strip the header on cross-origin redirects.

Because this is a highly unlikely scenario, we believe the severity of this vulnerability is low for almost all users. Out of an abundance of caution urllib3 will automatically strip the Proxy-Authorization header during cross-origin redirects to avoid the small chance that users are doing this on accident.

Users should use urllib3's proxy support or disable automatic redirects to achieve safe processing of the Proxy-Authorization header, but we still decided to strip the header by default in order to further protect users who aren't using the correct approach.

Affected usages

We believe the number of usages affected by this advisory is low. It requires all of the following to be true to be exploited:

  • Setting the Proxy-Authorization header without using urllib3's built-in proxy support.
  • Not disabling HTTP redirects.
  • Either not using an HTTPS origin server or for the proxy or target origin to redirect to a malicious origin.

Remediation

  • Using the Proxy-Authorization header with urllib3's ProxyManager.
  • Disabling HTTP redirects using redirects=False when sending requests.

Release notes

Sourced from urllib3's releases.

2.2.2

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support for 2023. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Changes

  • Added the Proxy-Authorization header to the list of headers to strip from requests when redirecting to a different host. As before, different headers can be set via Retry.remove_headers_on_redirect.
  • Allowed passing negative integers as amt to read methods of http.client.HTTPResponse as an alternative to None. (#3122)
  • Fixed return types representing copying actions to use typing.Self. (#3363)

Thank you for your support.

Changes

  • Fixed issue where InsecureRequestWarning was emitted for HTTPS connections when using Emscripten. (#3331)
  • Fixed HTTPConnectionPool.urlopen to stop automatically casting non-proxy headers to HTTPHeaderDict. This change was premature as it did not apply to proxy headers and HTTPHeaderDict does not handle byte header values correctly yet. (#3343)
  • Changed ProtocolError to InvalidChunkLength when response terminates before the chunk length is sent. (#2860)
  • Changed ProtocolError to be more verbose on incomplete reads with excess content. (#3261)

2.2.0

🖥️ urllib3 now works in the browser

🎉 This release adds experimental support for using urllib3 in the browser with Pyodide! 🎉

Thanks to Joe Marshall (@​joemarshall) for contributing this feature. This change was possible thanks to work done in urllib3 v2.0 to detach our API from http.client. Please report all bugs to the urllib3 issue tracker.

Changes

  • Added support for Emscripten and Pyodide, including streaming support in cross-origin isolated browser environments where threading is enabled. (#2951)
  • Added support for HTTPResponse.read1() method. (#3186)
  • Added rudimentary support for HTTP/2. (#3284)
  • Fixed issue where requests against urls with trailing dots were failing due to SSL errors when using proxy. (#2244)
  • Fixed HTTPConnection.proxy_is_verified and HTTPSConnection.proxy_is_verified to be always set to a boolean after connecting to a proxy. It could be None in some cases previously. (#3130)
