CVE-2026-45783: Improper Input Validation

libp2p is a JavaScript Implementation of libp2p networking stack. Prior to version 16.2.6, an unauthenticated remote peer can exhaust the disk storage of any @libp2p/kad-dht node running in server mode by sending an unbounded stream of PUTVALUE messages whose keys bypass all content validation. N...

CVE-2026-46541

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.4.0, iIn handledhtget, the DhtResults accumulator is only initialized when the first DHT record passes verification. If the first record fails from a malicious DHT...

CVE-2026-46541

CVE-2026-46541 (Nimiq network-libp2p): Before 1.4.0, DHT handling in handle_dht_get() sometimes did not initialize the DhtResults accumulator if the first DHT record failed verification. This caused all subsequent valid records to be discarded with “DHT inconsistent state” errors, enabling potent...

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...

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...

CVE-2026-40092

Summary: In Nimiq’s Rust-based stack, versions ≤ 1.3.0 of the nimiq-blockchain component are vulnerable to a crafted Kademlia DHT record containing a TaggedSigned with a signature field not exactly 64 bytes. When a victim node processes the record, the Ed25519 signature is parsed via Ed25519Signa...
