{"id":"CVE-2026-26316","aliases":["GHSA-pchc-86f6-8758"],"url":"https://o3.security/vulnerability/CVE-2026-26316","summary":"OpenClaw has BlueBubbles webhook auth bypass via loopback proxy trust","details":"### Summary\n\nIn 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.\n\n### Affected Packages / Versions\n\n- npm: `openclaw` `< 2026.2.13`\n- npm: `@openclaw/bluebubbles` `< 2026.2.13`\n\n### Details\n\nIf 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.\n\n### Fix Commit(s)\n\n- f836c385ffc746cb954e8ee409f99d079bfdcd2f\n- 743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a (defense-in-depth)\n\n### Mitigations\n\n- Set a non-empty BlueBubbles webhook password.\n- Avoid deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.\n\nThanks @MegaManSec (https://joshua.hu) of [AISLE Research Team](https://aisle.com/) for reporting.","published":"2026-02-19T21:28:33.454Z","modified":"2026-10-28T02:31:00.602752529Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.13"},{"ecosystem":"npm","name":"@openclaw/bluebubbles","fixedVersion":"2026.2.13"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a","label":"openclaw/openclaw@743f4b2"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.13"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26316.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-pchc-86f6-8758"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26316"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/f836c385ffc746cb954e8ee409f99d079bfdcd2f"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.12"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:00.602752529Z"}}
