Received Received - Intake
Unauthenticated Access in OpenClaw Nostr Plugin Enables Profile Manipulation

Publication date: 2026-03-05

Last updated on: 2026-03-11

Assigner: VulnCheck

Description
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.

Executive Summary

This vulnerability affects OpenClaw versions prior to 2026.2.12 when the optional Nostr plugin is enabled. It exposes unauthenticated HTTP endpoints that allow anyone to read and modify Nostr profiles without needing gateway authentication.

Specifically, remote attackers can access the endpoints /api/channels/nostr/:accountId/profile and /api/channels/nostr/:accountId/profile/import to read sensitive profile data, change Nostr profiles, persist malicious changes to the gateway configuration, and publish signed Nostr events using the bot's private key if the gateway HTTP port is accessible beyond localhost.

Impact Analysis

The vulnerability can lead to unauthorized disclosure of sensitive profile data and unauthorized modification of Nostr profiles.

Attackers can persist malicious changes to the gateway configuration and publish signed Nostr events using the bot's private key, potentially leading to impersonation or misuse of the bot.
