{"id":"CVE-2026-32896","aliases":["GHSA-5mx2-2mgw-x8rm"],"url":"https://o3.security/vulnerability/CVE-2026-32896","summary":"OpenClaw < 2026.2.21 - Unauthenticated Webhook Access via Passwordless Fallback in BlueBubbles Plugin","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: `<=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.","published":"2026-03-21T00:42:32.222Z","modified":"2026-10-28T02:31:03.490405155Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.21"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/283029bdea23164ab7482b320cb420d1b90df806","label":"openclaw/openclaw@283029b"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32896.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-unauthenticated-webhook-access-via-passwordless-fallback-in-bluebubbles-plugin"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/283029bdea23164ab7482b320cb420d1b90df806"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/6b2f2811dc623e5faaf2f76afaa9279637174590"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:03.490405155Z"}}
