nimiq/core-rs-albatross: Macro block proposal interlink bug

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, an elected validator proposer can send an election macro block whose header.interlink does not match the canonical next interlink. Honest validators accept that proposal in verify_macro_block_proposal() because the proposal path validates header shape, successor relation, proposer, body root, and state, but never checks the interlink binding for election blocks. The same finalized block is later rejected by verify_block() during push with InvalidInterlink. Because validators prevote and precommit the malformed header hash itself, the failure happens after Tendermint decides the block, not before voting. This issue has been patched in version 1.3.0.

对数据真实性的验证不充分

core-rs-albatross 数据伪造问题漏洞

core-rs-albatross是Nimiq开源的一个Albatross协议的Rust实现。 core-rs-albatross 1.3.0之前版本存在数据伪造问题漏洞，该漏洞源于未检查选举宏块的interlink绑定，可能导致接受无效区块。
