GHSA-33QG-7WPP-89CQ Rack::Session::Cookie secrets: decrypt failure fallback enables secretless session forgery and Marshal deserialization

Rack::Session::Cookie incorrectly handles decryption failures when configured with secrets:. If cookie decryption fails, the implementation falls back to a default decoder instead of rejecting the cookie. This allows an unauthenticated attacker to supply a crafted session cookie that is accepted ...
