### Impact A logic flaw in `BlockInclusionProof::is_block_proven` causes the function to return true without performing any cryptographic verification when `get_interlink_hops` yields an empty hop list. This occurs when the target block is at the election block position immediately preceding the election head's epoch. An attacker providing transaction inclusion proofs can forge a MacroBlock header for that epoch position and have it accepted as "proven" without any hash or signature verification. ### Patches [The patch for this vulnerability](https://github.com/nimiq/core-rs-albatross/pull/3705) is formally released as part of [v1.4.0](https://github.com/nimiq/core-rs-albatross/releases/tag/v1.4.0). ### Workarounds No Workarounds ### Resources See [PR](https://github.com/nimiq/core-rs-albatross/pull/3705).

AI coding agents often install or upgrade packages automatically in rust. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
