CVE-2026-34067

The CVE-2026-34067 issue affects the nimiq-transaction component in Nimiq’s Rust implementation. Before version 1.3.0, the function HistoryTreeProof::verify panics when a proof is malformed and the arrays history and positions have different lengths, due to the assertion in code. The proof origin...

CVE-2026-34067 nimiq-transaction vulnerable to panic via `HistoryTreeProof` length mismatch

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, HistoryTreeProof::verify panics on a malformed proof where history.len != positions.len due to asserteq!history.len, positions.len. The proof object is derived from untrusted p2...

CVE-2026-34066

The CVE affects the nimiq-blockchain Rust implementation. Before v1.3.0, HistoryStore::put_historic_txns asserts invariants on HistoricTransaction.block_number (must be within the macro block and same epoch). During history sync, a peer can influence the history input to Blockchain::push_history_...

CVE-2026-34066 nimiq-blockchain: Peer-triggerable panic during history sync

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. Prior to version 1.3.0, HistoryStore::puthistorictxns uses an assert! to enforce invariants about HistoricTransaction.blocknumber must be within the macro block being pushed and within the same epoch.

CVE-2026-34065 nimiq-primitives: Node crash due to missing interlink validation in election macro block proposals

nimiq-primitives contains primitives e.g., block, account, transaction to be used in Nimiq's Rust implementation. Prior to version 1.3.0, an untrusted p2p peer can cause a node to panic by announcing an election macro block whose validators set contains an invalid compressed BLS voting key. Hashi...

CVE-2026-34064

The CVE-2026-34064 issue affects Nimiq-account’s VestingContract in the Rust implementation. Before v1.3.0, VestingContract::can_change_balance can produce AccountError::InsufficientFunds and builds the error with balance = self.balance - min_cap; if min_cap > balance, Coin::sub underflows and...

CVE-2026-34064 nimiq-account: Vesting insufficient funds error can panic

nimiq-account contains account primitives to be used in Nimiq's Rust implementation. Prior to version 1.3.0, VestingContract::canchangebalance returns AccountError::InsufficientFunds when newbalance balance, the node crashes while trying to return an error. The mincap balance precondition is...
