SEVERITY

PATCHED VERSIONS

  • >= 1.1.1

DESCRIPTION

mysql-binuuid-rails 1.1.0 and earlier allows SQL Injection because it removes default string escaping for affected database columns. ActiveRecord does not explicitly escape the Binary data type (Type::Binary::Data) for mysql. mysql-binuuid-rails uses a data type that is derived from the base Binary type, except, it doesn’t convert the value to hex. Instead, it assumes the string value provided is a valid hex string and doesn’t do any checks on it.
