GMS-2020-447: Sensitive Data Exposure in rails-session-decoder

September 2, 2020

All versions of rails-session-decoder are missing verification of the Message Authentication Code appended to the cookies. This may lead to decryption of cipher text thus exposing encrypted information. No fix is currently available. Consider using an alternative module until a fix is made available.
