Authentication Bypass in OpenClaw BlueBubbles Webhook Enables Remote Injection

Publication date: 2026-03-05

Last updated on: 2026-03-11

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.12 contain a vulnerability in the BlueBubbles (optional plugin) webhook handler in which it authenticates requests based solely on loopback remoteAddress without validating forwarding headers, allowing bypass of configured webhook passwords. When the gateway operates behind a reverse proxy, unauthenticated remote attackers can inject arbitrary BlueBubbles message and reaction events by reaching the proxy endpoint.

Executive Summary

OpenClaw versions prior to 2026.2.12 have a vulnerability in the BlueBubbles optional plugin webhook handler. This vulnerability arises because the handler authenticates requests solely based on the loopback remoteAddress without validating forwarding headers. As a result, when the gateway is behind a reverse proxy, an unauthenticated remote attacker can bypass the configured webhook passwords.

This allows the attacker to inject arbitrary BlueBubbles message and reaction events by reaching the proxy endpoint.

Impact Analysis

This vulnerability can allow unauthenticated remote attackers to inject arbitrary messages and reaction events into the BlueBubbles system. This means attackers can impersonate legitimate users or manipulate message content without authorization.

Such unauthorized injections can lead to misinformation, disruption of communication, and potential trust issues within the affected environment.
