Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Published

The BlueBubbles webhook handler in OpenClaw versions prior to 2026.2.21 contains a passwordless fallback authentication path that allows unauthenticated webhook events in certain reverse-proxy or local routing configurations. Attackers can bypass webhook authentication by exploiting the loopback/proxy heuristics to send unauthenticated webhook events to the BlueBubbles plugin.

### Summary BlueBubbles webhook auth in the optional beta iMessage plugin allowed a passwordless fallback path. In some reverse-proxy/local routing setups, this could allow unauthenticated webhook events. ### Affected Component and Scope - Component: `extensions/bluebubbles` webhook handler - Scope: only deployments using the optional BlueBubbles plugin where webhook password auth was not configured for incoming webhook events ### Affected Packages / Versions - Package: `openclaw/openclaw` (npm) - Latest published npm version at triage time (2026-02-21): `2026.2.19-2` - Affected structured range: `<=2026.2.19-2` - Fixed on `main`; planned patched release: `2026.2.21` (`>=2026.2.21`) ### Details The vulnerable implementation had multiple auth branches, including a passwordless fallback with loopback/proxy heuristics. The fix now uses one authentication codepath: - inbound webhook token/guid must match `channels.bluebubbles.password` - webhook target matching is consolidated to shared plugin-sdk logic - BlueBubbles config validation now requires `password` when `serverUrl` is set ### Impact BlueBubbles is an optional beta iMessage plugin, and onboarding/channel-add flows already require a password. Practical exposure is mainly custom/manual configurations that omitted webhook password authentication. ### Remediation - Upgrade to a release that includes this patch (`>=2026.2.21`, planned). - Ensure BlueBubbles webhook delivery includes a matching password (`?password=<password>` or `x-password`). ### Fix Commit(s) - `6b2f2811dc623e5faaf2f76afaa9279637174590` - `283029bdea23164ab7482b320cb420d1b90df806` ### Release Process Note `patched_versions` is pre-set to the planned next release (`2026.2.21`) so once npm release is out, advisory publish can proceed without additional ticket edits. OpenClaw thanks @zpbrent for reporting.
