Description

OpenClaw versions 2026.3.22 before 2026.3.31 contain a signature verification bypass vulnerability in the Nostr DM ingress path that allows pairing challenges to be issued before event signature validation. An unauthenticated remote attacker can send forged direct messages to create pending pairing entries and trigger pairing-reply attempts, consuming shared pairing capacity and triggering bounded relay and logging work on the Nostr channel.
