Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of nostr-relay-pool before 0.44.3 can process events from a relay without first checking that the event's content, tags, author, and signature match its claimed event ID. A malicious relay could send a forged event that reuses the ID of a known database entry, and a collision in the verification cache could also let an unverified event pass as checked. Upgrade to nostr-relay-pool 0.44.3 or later, which verifies each event before policy checks, database lookup, or propagation.
