Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Insecure Transport: The AWS Auth V4 transport implementation previously ignored the 'ssl' connection parameter. This caused authenticated requests containing AWS credentials to fall back to insecure HTTP, exposing sensitive signatures and payloads to potential interception.
Insecure Defaults: The default Ansible deployment configuration bound the Elasticsearch instance to the public or local network instead of localhost. This exposed the unauthenticated datastore to unauthorized external network access.
