Overview
Affected versions of this package are vulnerable to Improper Validation of Certificate with Host Mismatch in components/octoprint, which uses custom Octoprint HTTP sessions. The default ssl parameter configuration uses the value False or None, which causes the SSL verification functionality to run and prevents information exposure. But in the Octoprint integration these default SSLContext settings can be bypassed by passing in use-ssl=true, which results in malicious connections appearing trusted and allowing MitM attacks.
