CVE-2026-33184 nimiq/core-rs-albatross: Discovery handshake limit could underflow and later provoke a deterministic overflow panic

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, the discovery handler accepts a peer-controlled limit during handshake and stores it unchanged. The immediate HandshakeAck path then honors lim...
