Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The nostr-relay-pool crate, versions before 0.44.2, cached signature verification results before the check ran, so a forged event with the same ID as a previously rejected event could skip verification. An attacker controlling or compromising a relay that an application connects to can inject events without valid signatures into that application's stored data, enabling impersonation of public keys. Upgrade to nostr-relay-pool 0.44.2 or later.
