Title

OpenClaw has BlueBubbles webhook auth bypass via loopback proxy trust

Summary

OpenClaw is a personal AI assistant. Prior to 2026.2.13, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (`127.0.0.1`, `::1`, `::ffff:127.0.0.1`) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled. Version 2026.2.13 contains a patch. Other mitigations include setting a non-empty BlueBubbles webhook password and avoiding deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.

Severity ?

Summary

OpenClaw BlueBubbles webhook auth bypass via loopback proxy trust

Details

Summary

In affected versions, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (127.0.0.1, ::1, ::ffff:127.0.0.1) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled.

Affected Packages / Versions

npm: openclaw < 2026.2.13
npm: @openclaw/bluebubbles < 2026.2.13

Details

If a deployment exposes the BlueBubbles webhook endpoint through a same-host reverse proxy (or an attacker can reach loopback via SSRF), an unauthenticated party may be able to inject inbound webhook events into the agent pipeline.

Fix Commit(s)

f836c385ffc746cb954e8ee409f99d079bfdcd2f
743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a (defense-in-depth)

Mitigations

Set a non-empty BlueBubbles webhook password.
Avoid deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.

      "value": "OpenClaw is a personal AI assistant. Prior to 2026.2.13, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (`127.0.0.1`, `::1`, `::ffff:127.0.0.1`) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled. Version 2026.2.13 contains a patch. Other mitigations include setting a non-empty BlueBubbles webhook password and avoiding deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication."
