In some reverse-proxy/local routing setups, this could allow unauthenticated webhook events.\n\n### Affected Component and Scope\n- Component: `extensions/bluebubbles` webhook handler\n- Scope: only deployments using the optional BlueBubbles plugin where webhook password auth was not configured for incoming webhook events\n\n### Affected Packages / Versions\n- Package: `openclaw/openclaw` (npm)\n- Latest published npm version at triage time (2026-02-21): `2026.2.19-2`\n- Affected structured range: `<=2026.2.19-2`\n- Fixed on `main`; planned patched release: `2026.2.21` (`>=2026.2.21`)\n\n### Details\nThe vulnerable implementation had multiple auth branches, including a passwordless fallback with loopback/proxy heuristics.\n\nThe fix now uses one authentication codepath:\n- inbound webhook token/guid must match `channels.bluebubbles.password`\n- webhook target matching is consolidated to shared plugin-sdk logic\n- BlueBubbles config validation now requires `password` when `serverUrl` is set\n\n### Impact\nBlueBubbles 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.\n\n### Remediation\n- Upgrade to a release that includes this patch (`>=2026.2.21`, planned).\n- Ensure BlueBubbles webhook delivery includes a matching password (`?password=<password>` or `x-password`).\n\n### Fix Commit(s)\n- `6b2f2811dc623e5faaf2f76afaa9279637174590`\n- `283029bdea23164ab7482b320cb420d1b90df806`\n\n### Release Process Note\n`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.\n\nOpenClaw thanks @zpbrent for reporting.","state":0,"publishedAt":"2026-03-03T21:35:56+00:00","modifiedAt":"2026-03-30T14:11:33.153599+00:00","affected":[{"ecosystem":"npm","name":"openclaw","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2026.2.21"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-5mx2-2mgw-x8rm","https://nvd.nist.gov/vuln/detail/CVE-2026-32896","https://github.com/openclaw/openclaw/commit/283029bdea23164ab7482b320cb420d1b90df806","https://github.com/openclaw/openclaw/commit/6b2f2811dc623e5faaf2f76afaa9279637174590","https://github.com/openclaw/openclaw","https://www.vulncheck.com/advisories/openclaw-unauthenticated-webhook-access-via-passwordless-fallback-in-bluebubbles-plugin"],"sourceUrl":"https://github.com/advisories/GHSA-5mx2-2mgw-x8rm","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-5mx2-2mgw-x8rm","identifiers":["GHSA-5mx2-2mgw-x8rm","CVE-2026-32896"]},"retained":false,"historicalAffected":[]},{"revision":"251fb630168145fab8856076228c229f","observedAt":"2026-10-24T13:17:17.793+00:00","statement":{"source":"osv","id":"GHSA-vh4c-j2xv-9pv9","aliases":[],"title":"Duplicate Advisory: OpenClaw: BlueBubbles beta plugin webhook auth hardening (remove passwordless fallback)","description":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-5mx2-2mgw-x8rm.
