Bug: Upgrading urllib3 to 2.6.0 with requests==2.28.1 causes AttributeError due to missing HTTPResponse methods.
_{Severity: CRITICAL | Confidence: High}

🔍 Detailed Analysis

Upgrading urllib3 to version 2.6.0 introduces an incompatibility with the pinned requests version 2.28.1. urllib3 2.6.0 removed HTTPResponse.getheaders() and HTTPResponse.getheader(), which requests 2.28.1 internally relies on in its HTTPAdapter.build_response() method. This will lead to an AttributeError: 'HTTPResponse' object has no attribute 'getheaders' whenever an HTTP request is made using requests.get(), causing the application to crash as there is no error handling.

💡 Suggested Fix

Upgrade requests to version 2.30.0 or newer, which officially supports urllib3 2.x. Alternatively, downgrade urllib3 to a 1.x version compatible with requests==2.28.1.

Potential issue: Upgrading `urllib3` to version 2.6.0 introduces an incompatibility with
the pinned `requests` version 2.28.1. `urllib3` 2.6.0 removed
`HTTPResponse.getheaders()` and `HTTPResponse.getheader()`, which `requests` 2.28.1
internally relies on in its `HTTPAdapter.build_response()` method. This will lead to an
`AttributeError: 'HTTPResponse' object has no attribute 'getheaders'` whenever an HTTP
request is made using `requests.get()`, causing the application to crash as there is no
error handling.
