CVE-2026-34067

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-2026-34065

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-2026-34063

Nimiq's network-libp2p is a Nimiq network implementation based on libp2p. Prior to version 1.3.0, network-libp2p discovery uses a libp2p ConnectionHandler state machine. the handler assumes there is at most one inbound and one outbound discovery substream per connection. if a remote peer...

CVE-2026-34068 nimiq-transaction: UpdateValidator transactions allows voting key change without proof-of-knowledge

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 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. During histo...
