{"id":"GHSA-9p38-94jf-hgjj","summary":"OpenClaw has macOS `system.run` allowlist bypass via quoted command substitution","details":"### Summary\nIn OpenClaw's macOS node-host path, `system.run` allowlist parsing in `security=allowlist` mode failed to reject command substitution tokens when they appeared inside double-quoted shell text.\n\nBecause of that gap, payloads like `echo \"ok $(id)\"` could be treated as allowlist hits (first executable token `echo`) while still executing non-allowlisted subcommands through shell substitution.\n\n### Affected Packages / Versions\n- Package: npm `openclaw`\n- Latest published affected version: `2026.2.21-2`\n- Affected range: `\u003c= 2026.2.21-2`\n- Patched version (planned next release): `2026.2.22`\n\nNotes:\n- Default installs are not affected (`security=deny` by default).\n- The issue requires opting into `security=allowlist` on the macOS node-host path.\n\n### Impact\nApproval/authorization bypass in allowlist mode that can lead to unintended command execution on the node host.\n\n### Preconditions\n- Target uses macOS node-host / companion-app execution path.\n- Exec approvals set to `security=allowlist`.\n- Ask mode is `on-miss` or `off`.\n- Allowlist contains a benign executable used in a shell wrapper flow (for example `/bin/echo`).\n\n### Reproduction (example)\nUse a shell-wrapper command where the visible executable is allowlisted but the quoted payload contains substitution:\n\n- command argv: `/bin/sh -lc 'echo \"ok $(/usr/bin/id \u003e /tmp/openclaw-poc-rce)\"'`\n- allowlist pattern includes `/bin/echo`\n\nBefore the fix, allowlist analysis could resolve this as allowlisted while shell substitution still executed.\n\n### Remediation\n- Upgrade to `2026.2.22` (or newer) when released.\n- Temporary mitigation: set ask mode to `always` or set security mode to `deny`.\n\n### Fix Commit(s)\n- `90a378ca3a9ecbf1634cd247f17a35f4612c6ca6`\n\n### Release Process Note\n`patched_versions` is pre-set to planned next release `2026.2.22`. After npm release is out, advisory can be published directly.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-22179"],"modified":"2026-03-19T18:47:22.965807Z","published":"2026-03-03T21:41:12Z","database_specific":{"nvd_published_at":"2026-03-18T02:16:22Z","cwe_ids":["CWE-78"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-03T21:41:12Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-9p38-94jf-hgjj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22179"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/90a378ca3a9ecbf1634cd247f17a35f4612c6ca6"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-allowlist-bypass-via-command-substitution-in-system-run"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-9p38-94jf-hgjj/GHSA-9p38-94jf-hgjj.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
