Según Protos, los desarrolladores de btc-42">Bitcoin Core revelaron recientemente una vulnerabilidad de alto riesgo numerada como CVE-2024-52911, que afecta a las versiones 0.14.1 a 28.4, permitiendo a los mineros bloquear remotamente los nodos de otros usuarios y ejecutar código mediante la minería de bloques especialmente diseñados.
La vulnerabilidad fue descubierta y revelada de manera responsable por el desarrollador Cory Fields en noviembre de 2024. La corrección se integró en diciembre de ese año y se lanzó con la versión v29 en abril de 2025. La última serie de versiones vulnerables 28.x fue descontinuada el 19 de abril de 2026.
Sin embargo, dado que la actualización de los nodos completos de Bitcoin es voluntaria, se estima que alrededor del 43% de los nodos aún ejecutan el software de la versión antigua vulnerable, enfrentando riesgos potenciales. Afortunadamente, el costo de implementar tal ataque es extremadamente alto—los mineros necesitarían asignar una potencia computacional significativa para minar bloques inválidos que no generan recompensas de bloque—por lo que es probable que nunca se haya explotado en la práctica.
