CVE-2026-33471: Improper Input Validation

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...
