CVE-2026-41301
OpenClaw 2026.3.22 < 2026.3.31 - Forged Nostr DM Pairing State Creation via Signature Verification Bypass
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.

OpenClaw: Forged Nostr DMs could create pairing state before signature verification
Summary
Before OpenClaw 2026.3.31, the Nostr DM ingress path could issue pairing challenges before validating the event signature. A forged DM could create a pending pairing entry and trigger a pairing-reply attempt before signature rejection.
Impact
An unauthenticated remote sender could consume shared pairing capacity and trigger bounded relay/logging work on the Nostr channel. This issue did not grant message decryption, pairing approval, or broader authorization bypass.
