Overview
Affected versions of this package are vulnerable to Uncaught Exception through the Chain::push process in the non-finalized state, which updates the tx_loc_by_hash index before performing duplicate shielded-nullifier checks. An attacker can cause the node process to abort by submitting a block that repeats a shielded transaction from its non-finalized parent, leading to a panic and termination of the process. This is only exploitable if the node is processing blocks past the checkpoint height with NU5 or later activated and the attacker is able to mine or broadcast blocks as described.
