{"id":"CVE-2026-22170","aliases":["GHSA-jwf4-8wf4-jf2m"],"url":"https://o3.security/vulnerability/CVE-2026-22170","summary":"OpenClaw < 2026.2.22 BlueBubbles - Access Control Bypass via Empty allowFrom Configuration","details":"### Summary\nBlueBubbles is an optional OpenClaw channel plugin. A configuration-sensitive access-control mismatch allowed DM senders to be treated as authorized when `dmPolicy` was `pairing` or `allowlist` and `allowFrom` was empty/unset.\n\n### Severity Rationale (Medium)\nSeverity is set to **medium** because:\n- this affects an optional plugin, not core messaging surfaces;\n- many deployments use owner-controlled/private BlueBubbles identities with limited external reachability;\n- practical exploitability depends on an untrusted sender being able to reach that specific BlueBubbles account identifier.\n\nIn typical personal/self-hosted BlueBubbles setups, the mapped Apple identity is single-owner and not broadly reachable, so this is usually low practical risk.\n\nRisk is higher in deployments where the identifier is publicly reachable and/or agent tool permissions are broad.\n\n### Technical Details\n1. BlueBubbles DM policy defaults to `pairing` (`dmPolicy ?? \"pairing\"`).\n2. Effective allowlist can be empty (`effectiveAllowFrom`).\n3. DM/reaction authorization called `isAllowedBlueBubblesSender(...)`.\n4. That delegated to shared `isAllowedParsedChatSender(...)`, which previously returned `true` for empty allowlists.\n5. Result: unknown senders could bypass intended pairing/allowlist gating when `allowFrom` was empty.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Vulnerable versions: `<= 2026.2.21-2`\n- Planned fixed version: `2026.2.22`\n\n### Fix\nThe shared parsed-chat allowlist helper now fails closed on empty allowlists, restoring expected BlueBubbles DM gating behavior. BlueBubbles inbound gating was also refactored to use one shared DM/group decision helper for both message and reaction paths to reduce future drift.\n\n### Fix Commit(s)\n- `9632b9bcf032c5f2280c3103961fde912ab1f920`\n- `2ba6de7eaad812e5e8603018e14e54e96bdd57dd`\n- `51c0893673de8e5cea64e64351dbfa4680ba0dec`\n- `4540790cb62412676f7b61cfc6e47443f84a251e`\n\nOpenClaw thanks @tdjackey for reporting.","published":"2026-03-18T01:34:18.300Z","modified":"2026-08-12T03:51:29.441539641Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.22"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/2ba6de7eaad812e5e8603018e14e54e96bdd57dd","label":"openclaw/openclaw@2ba6de7"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22170.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-jwf4-8wf4-jf2m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22170"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-bluebubbles-access-control-bypass-via-empty-allowfrom-configuration"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/2ba6de7eaad812e5e8603018e14e54e96bdd57dd"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/4540790cb62412676f7b61cfc6e47443f84a251e"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/51c0893673de8e5cea64e64351dbfa4680ba0dec"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/9632b9bcf032c5f2280c3103961fde912ab1f920"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.441539641Z"}}
