Zebra before 6.1.0 contains an inefficient algorithmic complexity vulnerability in remaining transaction value that clones the entire block-level spent-UTXO map per transaction during contextual verification. Attackers can mine or seed the mempool with roughly 26,000 minimal single-input transactions in one block, stalling every validating node for over 52 seconds.
