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...
