Descriptions
Puma is a Ruby/Rack web server built for parallelism. Prior to `puma` version `5.6.2`, `puma` may not always call `close` on the response body. Rails, prior to version `7.0.2.2`, depended on the response body being closed in order for its `CurrentAttributes` implementation to work correctly. The combination of these two behaviors (Puma not closing the body + Rails' Executor implementation) causes information leakage. This problem is fixed in Puma versions 5.6.2 and 4.3.11. This problem is fixed in Rails versions 7.02.2, 6.1.4.6, 6.0.4.6, and 5.2.6.2. Upgrading to a patched Rails _or_ Puma version fixes the vulnerability.
Puma es un servidor web Ruby/Rack construido para el paralelismo. versiones anteriores a "puma" "5.6.2", "puma" no siempre llamaba a "close" en el cuerpo de la respuesta. Rails, versiones anteriores a "7.0.2.2", dependía de que el cuerpo de la respuesta estuviera cerrado para que su implementación de "CurrentAttributes" funcionara correctamente. La combinación de estos dos comportamientos (que Puma no cierre el cuerpo + la implementación del ejecutor de Rails) causa un filtrado de información. Este problema ha sido solucionado en Puma versiones 5.6.2 y 4.3.11. Este problema se ha solucionado en las versiones de Rails versiones 7.02.2, 6.1.4.6, 6.0.4.6 y 5.2.6.2. La actualización a una versión parcheada de Rails _o_ de Puma corrige esta vulnerabilidad
A flaw was found in Puma and Rails rubygems when response bodies were not closed under certain situations. This flaw allows an attacker, by iterating certain requests, to take advantage of this issue and affect CurrentAttributes, leading to leaked data.
