CVE-2026-44505

The CVE affects Nimiq’s network-libp2p component (Rust) used in the Albatross-based PoS implementation. Before v1.4.0, when a peer returns a FoundRecord, the code verified the record via dht_verifier.verify and, on verifier error, logged and returned early without completing the oneshot used by N...

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.4.0, when LightBlockchain::rebranch adopts a fork chain whose tip is a macro block checkpoint or election, it only updates self.head but fails to update self.macro...

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-2026-34062

nimiq-libp2p is a Nimiq network implementation based on libp2p. Prior to version 1.3.0, MessageCodec::readrequest and readresponse call readtoend on inbound substreams, so a remote peer can send only a partial frame and keep the substream open. because Behaviour::new also sets...

CVE-2026-34069

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the...

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-2026-40092

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. In versions 1.3.0 and below, a malicious network peer can crash any Nimiq full node by publishing a crafted Kademlia DHT record. The maliciously crafted record would contain a TaggedSigned with a signature field...

nimiq-blockchain: Genesis batch set request

Impact A remote peer can crash any full node by sending a RequestBatchSet message containing the genesis block's hash. The handler calls getepochchunks which iterates backwards through macro blocks using Policy::macroblockbefore. When it reaches the genesis block number, macroblockbefore panics...

GHSA-H9CC-W26M-J342 nimiq-keys: Denial of service in Ed25519 multisig delinearization via invalid curve points

Impact A denial-of-service vulnerability exists in the Ed25519 multisig delinearization code path. Ed25519PublicKey::delinearize in keys/src/multisig/mod.rs called .unwrap on curve point decompression, which panics when a public key is constructed from 32 bytes that do not represent a valid point...
