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...

GHSA-6973-8887-87FF nimiq-block has skip block quorum bypass via out-of-range BitSet indices & u16 truncation

Impact 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. If an attacker can get a SkipBlockProof verified where MultiSignature.signers contains out-of-range indices spaced by 65536, these...

CVE-2026-33471

CVE-2026-33471 affects nim i q/core-rs-albatross (Rust Nimiq PoS) prior to v1.3.0. The vulnerability arises in SkipBlockProof::verify, which checks quorum using BitSet.len() and then casts each index (slot as u16) for lookup. Attackers can craft a SkipBlockProof where out-of-range indices spaced ...

Nimiq 输入验证错误漏洞

Nimiq is an open-source implementation of the Albatross protocol in Rust. Prior to Nimiq 1.3.0, there was a vulnerability related to input validation. This vulnerability stemmed from the use of BitSet.len in SkipBlockProof::verify, which calculates the for slot checks. This process involves...
