Prior to version 1.2.2, a malicious or compromised validator that is elected as proposer can publish a macro block proposal where `header.body_root` does not match the actual macro body hash. The proposal can pass proposal verification because the macro proposal verification path validates the header but does not validate the binding `body_root == hash(body)`; later code expects this binding and may panic on mismatch, crashing validators. Note that the impact is only for validator nodes. The patch for this vulnerability is formally released as part of v1.2.2. The patch adds the corresponding body root verification in the proposal checks. No known workarounds are available."}, {"lang": "es", "value": "nimiq/core-rs-albatross es una implementaci\u00f3n en Rust del protocolo Nimiq Proof-of-Stake basado en el algoritmo de consenso Albatross. Antes de la versi\u00f3n 1.2.2, un validador malicioso o comprometido que es elegido como proponente puede publicar una propuesta de macrobloque donde `header.body_root` no coincide con el hash real del cuerpo del macrobloque. La propuesta puede pasar la verificaci\u00f3n de la propuesta porque la ruta de verificaci\u00f3n de la macropropuesta valida el encabezado pero no valida la vinculaci\u00f3n `body_root == hash(body)`; el c\u00f3digo posterior espera esta vinculaci\u00f3n y puede entrar en p\u00e1nico en caso de falta de coincidencia, provocando la ca\u00edda de los validadores.
