{"id":"GHSA-pchc-86f6-8758","summary":"OpenClaw 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` `\u003c 2026.2.13`\n- npm: `@openclaw/bluebubbles` `\u003c 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.","aliases":["CVE-2026-26316"],"modified":"2026-02-20T16:58:43.992121Z","published":"2026-02-17T21:33:51Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-02-17T21:33:51Z","nvd_published_at":"2026-02-19T22:16:47Z","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openclaw/openclaw/commit/743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a"},{"type":"WEB","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"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.13"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.13"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-pchc-86f6-8758/GHSA-pchc-86f6-8758.json"}},{"package":{"name":"@openclaw/bluebubbles","ecosystem":"npm","purl":"pkg:npm/%40openclaw/bluebubbles"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.13"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-pchc-86f6-8758/GHSA-pchc-86f6-8758.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
