The problem has been fixed by comparing sent and calculated signature in constant time, using `Rack::Utils.secure_compare`. Users using the `derivation_endpoint` plugin are urged to upgrade to Shrine 3.3.0 or greater. A possible workaround is provided in the linked advisory."},{"lang":"es","value":"En Shrine versiones anteriores a 3.3.0, cuando se usa el plugin \"derivation_endpoint\", es posible que el atacante use un ataque de sincronización para adivinar la firma de la URL de derivación.
