Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Discovery (tech.pegasys.discovery:discovery) versions before 0.4.5 reuse the same AES-GCM nonce for the whole session instead of generating one per message. An attacker who can observe the traffic can exploit this to recover the session key, which is used to communicate with a single peer; the node's private key is not exposed. Upgrade to version 0.4.5 or later. No workaround is listed.
