CVE-2026-46539 nimiq-primitives: BlockInclusionProof interlink issue when hops are empty

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 logic flaw in BlockInclusionProof::isblockproven causes the function to return true without performing any cryptographic verification when getinterlinkhops...

CVE-2026-33471 nimiq-block has skip block quorum bypass via out-of-range BitSet indices & u16 truncation

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...

CVE-2026-34069

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the...
