Overview

Affected versions of this package are vulnerable to Race Condition due to the incorrect implementation of consensus rules as outlined in BIP 68 and BIP 112, specifically by treating the transaction version as a signed integer instead of unsigned. This misinterpretation can lead to a chain split and potential loss of funds by creating a discrepancy in the network consensus.
