What is CVE-2026-46543?

A vulnerability in the Nimiq Proof-of-Stake protocol allows remote attackers to crash full nodes by sending a RequestBatchSet message that includes the genesis block's hash. This issue arises during the processing of epoch chunks, where a panic occurs if it attempts to access macro blocks before the genesis block. To mitigate this risk, users are advised to upgrade to version 1.5.0, which contains the necessary patch.

Affected Version(s)
