{"id":"GHSA-jj82-76v6-933r","summary":"OpenClaw's exec allowlist wrapper analysis did not unwrap env/shell dispatch chains","details":"### Summary\n`system.run` exec allowlist analysis treated wrapper binaries as the effective executable and did not fully unwrap `env`/shell-dispatch wrappers.\n\nThis allowed wrapper-smuggled payloads (for example `env bash -lc ...`) to satisfy an allowlist entry for the wrapper while executing non-allowlisted commands.\n\n### Impact\nOn affected versions, an actor who can trigger `system.run` requests under an allowlist policy could bypass intended allowlist restrictions by routing execution through wrapper binaries.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.21-2`\n- Patched in next release: `2026.2.22` (pre-set below so publish can happen immediately after npm release)\n\n### Fix Commit(s)\n- `2b63592be57782c8946e521bc81286933f0f99c7`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`\u003e= 2026.2.22`).\n\nAfter npm `2026.2.22` is published, this advisory can be published directly without further metadata edits.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-27566"],"modified":"2026-03-20T21:47:59.064139Z","published":"2026-03-03T23:13:51Z","database_specific":{"github_reviewed":true,"severity":"HIGH","nvd_published_at":null,"cwe_ids":["CWE-78","CWE-863"],"github_reviewed_at":"2026-03-03T23:13:51Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-jj82-76v6-933r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27566"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/2b63592be57782c8946e521bc81286933f0f99c7"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-allowlist-bypass-via-wrapper-binary-unwrapping-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-jj82-76v6-933r/GHSA-jj82-76v6-933r.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
