How to fix?

Upgrade requests to version 2.32.0 or higher.

Overview

Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation when making requests through a Requests Session. An attacker can bypass certificate verification by making the first request with verify=False, causing all subsequent requests to ignore certificate verification regardless of changes to the verify value.

Notes:

  1. For requests<2.32.0, avoid setting verify=False for the first request to a host while using a Requests Session.

  2. For requests<2.32.0, call close() on Session objects to clear existing connections if verify=False is used.
