Descriptions

In Bitcoin Core through 26.0 and Bitcoin Knots before 25.1.knots20231115, datacarrier size limits can be bypassed by obfuscating data as code (e.g., with OP_FALSE OP_IF), as exploited in the wild by Inscriptions in 2022 and 2023. NOTE: although this is a vulnerability from the perspective of the Bitcoin Knots project, some others consider it "not a bug."

En Bitcoin Core hasta 26.0 y Bitcoin Knots anteriores a 25.1.knots20231115, los límites de tamaño del portador de datos se pueden eludir ofuscando los datos como código (por ejemplo, con OP_FALSE OP_IF), tal como lo explotó Inscriptions en 2022 y 2023.
