Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Plain-text HTTP error responses with status codes >= 400 were treated as successful responses instead of throwing an exception, allowing invalid or failed authentication attempts to bypass security checks.
Auth Bypass: Flawed error-code checking logic prevented the SDK from throwing an Auth0Error when an 'mfa_required' error was returned, potentially allowing users to bypass multi-factor authentication requirements.
Denial of Service: The response processor could crash with a TypeError if the deserialized JSON response was an unexpected type (like a list) instead of a dictionary, leading to an application-wide denial of service when handling malformed upstream responses.
