  "title": "Excon: redact additional sensitive/risky headers when following redirects",
  "description": "Excon is usable, fast, simple HTTP 1.1 for Ruby. Prior to 1.5.0, Excon\u0027s RedirectFollower middleware failed to strip additional sensitive headers when following redirects and did not provide a custom list of headers to strip. This could cause inadvertent leakage of sensitive data when the initial request includes header information that is not intended for the new target. This issue is fixed in version 1.5.0.",
