The Native-Signature Boundary in Post-Quantum Distributed Authorization

Post-quantum signature migration poses a distinct systems problem when authorization is distributed among multiple parties. In native threshold signing, the signature algorithm may determine key generation, share state, preprocessing, interaction, combination, refresh, and recovery. Architectures...

CVE-2026-46542 nimiq-keys: Denial of service in Ed25519 multisig delinearization via invalid curve points

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.4.0, a denial-of-service vulnerability exists in the Ed25519 multisig delinearization code path. Ed25519PublicKey::delinearize in keys/src/multisig/mod.rs called...

CVE-2026-46542

CVE-2026-46542 affects Nimiq’s Rust implementation prior to v1.4.0, where Ed25519 public-key handling in multisig could cause a denial-of-service crash. The issue occurs because Ed25519PublicKey::delinearize() calls unwrap() on curve point decompression, panicking when a 32-byte input does not re...

CVE-2026-33471

nimiq-block contains block primitives to be used in Nimiq's Rust implementation. SkipBlockProof::verify computes its quorum check using BitSet.len, then iterates BitSet indices and casts each usize index to u16 slot as u16 for slot lookup. Prior to version 1.3.0, if an attacker can get a...

Insecure String Comparison

zencashjs uses an insecure string comparison. This is due to a clash of address prefixes for testnet P2PKH and mainnet P2SH addresses. The package interprets transactions sent to a zt P2SH address on mainnet as P2PKH transactions erroneously. Any funds sent to a mainnet P2SH multisignature addres...
