CVE-2026-28450
OpenClaw < 2026.2.12 - Unauthenticated Profile Tampering via Nostr Plugin HTTP Endpoints
OpenClaw versions prior to 2026.2.12 with the optional Nostr plugin enabled expose unauthenticated HTTP endpoints at /api/channels/nostr/:accountId/profile and /api/channels/nostr/:accountId/profile/import that allow reading and modifying Nostr profiles without gateway authentication. Remote attackers can exploit these endpoints to read sensitive profile data, modify Nostr profiles, persist malicious changes to gateway configuration, and publish signed Nostr events using the bot's private key when the gateway HTTP port is accessible beyond localhost.

OpenClaw's unauthenticated Nostr profile HTTP endpoints allow remote profile/config tampering
Summary
The OpenClaw Nostr channel plugin (optional, disabled by default, installed separately) exposes profile management HTTP endpoints under /api/channels/nostr/:accountId/profile (GET/PUT) and /api/channels/nostr/:accountId/profile/import (POST). In affected versions, these routes were dispatched via the gateway plugin HTTP layer without requiring gateway authentication, allowing unauthenticated remote callers to read or mutate the Nostr profile and persist changes to the gateway config. Profile updates are also published as a signed Nostr kind:0 event using the bot's private key.
Deployments that do not have the Nostr plugin installed and enabled are not impacted.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.9 - Fixed versions:
>= 2026.2.12 - Scope note: only affects deployments with the optional
@openclaw/nostrplugin installed and enabled
Details
This is exploitable when the gateway HTTP port is reachable beyond localhost (for example: bound to 0.0.0.0, exposed on a LAN, behind a reverse proxy, or via Tailscale Funnel/Serve).
Unauthenticated callers could update the Nostr profile and persist the new profile in the gateway config.
Mitigation
Upgrade to openclaw 2026.2.12 or later.
As a temporary mitigation, restrict gateway HTTP exposure (bind loopback-only and/or enforce network-layer access controls) until upgraded.
Fix
Gateway now requires gateway authentication for plugin HTTP requests under /api/channels/* before dispatching to plugin handlers.
