Summary
SSL validation for outgoing requests in Home Assistant Core and used libs not correct
Details

Home Assistant Core is an open source home automation that puts local control and privacy first. Affected versions are subject to a potential man-in-the-middle attacks due to missing SSL certificate verification in the project codebase and used third-party libraries. In the past, aiohttp-session/request had the parameter verify_ssl to control SSL certificate verification. This was a boolean value. In aiohttp 3.0, this parameter was deprecated in favor of the ssl parameter. Only when ssl is set to None or provided with a correct configured SSL context the standard SSL certificate verification will happen. When migrating integrations in Home Assistant and libraries used by Home Assistant, in some cases the verify_ssl parameter value was just moved to the new ssl parameter. This resulted in these integrations and 3rd party libraries using request.ssl = True, which unintentionally turned off SSL certificate verification and opened up a man-in-the-middle attack vector. This issue has been addressed in version 2024.1.6 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
