{"id":"GHSA-xgf2-vxv2-rrmg","summary":"OpenClaw's shell startup env injection bypasses system.run allowlist intent (RCE class)","details":"### Summary\n`system.run` environment sanitization allowed shell-startup env overrides (`HOME`, `ZDOTDIR`) that can execute attacker-controlled startup files before allowlist-evaluated command bodies.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.21-2` (latest published vulnerable version)\n- Planned patched version: `\u003e= 2026.2.22`\n\n### Technical Details\nIn affected versions:\n- Env sanitization blocked many dangerous keys, but not startup-sensitive override keys (`HOME`, `ZDOTDIR`) in host exec env paths.\n- Shell-wrapper analysis for allowlist mode models command bodies, but not shell startup side effects.\n- Runtime execution used sanitized env, so attacker-provided startup-key overrides could run hidden startup payloads first.\n\nObserved exploit vectors:\n- `HOME` + `bash -lc` + malicious `.bash_profile`\n- `ZDOTDIR` + `zsh -c` + malicious `.zshenv`\n\n### Fix Commit(s)\n- `c2c7114ed39a547ab6276e1e933029b9530ee906`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`\u003e= 2026.2.22`). After the npm release is published, this advisory can be published directly.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-32056"],"modified":"2026-03-30T13:56:22.016195Z","published":"2026-03-03T22:12:51Z","database_specific":{"github_reviewed_at":"2026-03-03T22:12:51Z","nvd_published_at":null,"cwe_ids":["CWE-15","CWE-78"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-xgf2-vxv2-rrmg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32056"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/c2c7114ed39a547ab6276e1e933029b9530ee906"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-remote-code-execution-via-shell-startup-environment-variable-injection-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-xgf2-vxv2-rrmg/GHSA-xgf2-vxv2-rrmg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
