CVE-2026-34067

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, HistoryTreeProof::verify panics on a malformed proof where history.len != positions.len due to asserteq!history.len, positions.len. The proof object is derived from untrusted p2...

CVE-2026-34068 nimiq-transaction: UpdateValidator transactions allows voting key change without proof-of-knowledge

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, the staking contract accepts UpdateValidator transactions that set newvotingkey=Some... while omitting newproofofknowledge. this skips the proof-of-knowledge requirement that is...

CVE-2026-34068

Summary (CVE-2026-34068) Nimiq-transaction’s staking contract (Rust) prior to v1.3.0 accepts UpdateValidator transactions that set new_voting_key=Some(...) without including new_proof_of_knowledge, bypassing the PoK requirement used to prevent BLS rogue-key attacks in aggregated signatures. Since...

CVE-2026-34067 nimiq-transaction vulnerable to panic via `HistoryTreeProof` length mismatch

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, HistoryTreeProof::verify panics on a malformed proof where history.len != positions.len due to asserteq!history.len, positions.len. The proof object is derived from untrusted p2...

CVE-2026-34067

The CVE-2026-34067 issue affects the nimiq-transaction component in Nimiq’s Rust implementation. Before version 1.3.0, the function HistoryTreeProof::verify panics when a proof is malformed and the arrays history and positions have different lengths, due to the assertion in code. The proof origin...

PT-2026-34554

Impact HistoryTreeProof::verify panics on a malformed proof where history.len != positions.len due to assert eq!history.len, positions.len. The proof object is derived from untrusted p2p responses ResponseTransactionsProof.proof and is therefore attacker-controlled at the network boundary until...

CVE-2026-34068: Improper Verification of Cryptographic Signature

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, the staking contract accepts UpdateValidator transactions that set newvotingkey=Some... while omitting newproofofknowledge. this skips the proof-of-knowledge requirement that is...

CVE-2026-34067: Reachable Assertion

nimiq-transaction provides the transaction primitive to be used in Nimiq's Rust implementation. Prior to version 1.3.0, HistoryTreeProof::verify panics on a malformed proof where history.len != positions.len due to asserteq!history.len, positions.len. The proof object is derived from untrusted p2...
