CVE-2026-34065: nimiq-primitives: Node crash due to missing interlink validation in election macro block proposals
(updated )
An untrusted p2p peer can cause a node to panic by announcing an election macro block whose validators set contains an invalid compressed BLS voting key.
Hashing an election macro header hashes validators and reaches Validators::voting_keys(), which calls validator.voting_key.uncompress().unwrap() and panics on invalid bytes.
