The protection against invalid header values should not leak their
content in the error message. Exceptions are commonly logged, sent to
third-party error monitoring systems, or published in internal
communication/messenger systems. A range of HTTP headers, like
Authorization
,Api-Key
, or similar, contain sensitive informationwhich should not be sent to such public destinations.
Thank you for excon, a great library!
The protection against invalid header values is helpful, but we accidentally leaked an API token today (exception -> Bugsnag -> Slack) which was passed from an
ENV["API_TOKEN"]
environment variable.
