CVE-2026-33184 is a high-severity flaw (CVSS 7.5) affecting nimiq proof-of-stake. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 limit = 0 and returns zero contacts, which makes the session look benign. Later, after the same session reaches Established, the periodic update path comput
