{"id":"GHSA-5mx2-2mgw-x8rm","summary":"OpenClaw: BlueBubbles beta plugin webhook auth hardening (remove passwordless fallback)","details":"### Summary\nBlueBubbles 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.\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: `\u003c=2026.2.19-2`\n- Fixed on `main`; planned patched release: `2026.2.21` (`\u003e=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 (`\u003e=2026.2.21`, planned).\n- Ensure BlueBubbles webhook delivery includes a matching password (`?password=\u003cpassword\u003e` 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.","aliases":["CVE-2026-32896"],"modified":"2026-03-30T14:11:33.153599Z","published":"2026-03-03T21:35:56Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-03T21:35:56Z","nvd_published_at":null,"cwe_ids":["CWE-306"]},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-5mx2-2mgw-x8rm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32896"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/283029bdea23164ab7482b320cb420d1b90df806"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/6b2f2811dc623e5faaf2f76afaa9279637174590"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-unauthenticated-webhook-access-via-passwordless-fallback-in-bluebubbles-plugin"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.21"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-5mx2-2mgw-x8rm/GHSA-5mx2-2mgw-x8rm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"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"}]}
