CVE-2026-41301 Details
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.
A vulnerability allowing signature verification bypass has been identified in OpenClaw versions 2026.3.22 prior to 2026.3.31. This issue occurs in the Nostr direct message (DM) ingress path, where pairing challenges can be issued before validating event signatures. As a result, an unauthenticated remote attacker could send forged direct messages that create pending pairing entries and trigger pairing-reply attempts. This exploitation consumes shared pairing capacity and generates additional relay and logging work on the Nostr channel.
Users can update to OpenClaw version 2026.3.31 or later, where this vulnerability has been patched.
