{"id":"GHSA-mqr9-vqhq-3jxw","summary":"OpenClaw Windows Scheduled Task script generation allowed local command injection via unsafe cmd argument handling","details":"### Summary\nOpenClaw Windows Scheduled Task script generation allowed unsafe argument handling in generated `gateway.cmd` files. In vulnerable versions, cmd metacharacter-only values could be emitted without safe quoting/escaping, which could lead to unintended command execution when the scheduled task runs.\n\n### Details\nThe issue affected Windows daemon startup script generation in `src/daemon/schtasks.ts`.\n\nVulnerable behavior included:\n- Incomplete cmd argument quoting for metacharacter-only values.\n- Incomplete handling of cmd expansion-sensitive characters in script arguments.\n- Missing CR/LF guards for script-rendered fields.\n\nThe fix hardens Windows script generation by:\n- Separating schtasks argument quoting from batch script argument quoting.\n- Quoting cmd metacharacter arguments and escaping `%` / `!` expansion cases.\n- Rejecting CR/LF in command arguments, task descriptions, and rendered environment assignments.\n- Adding regression tests for metacharacter and line-break injection paths.\n\n### Impact\nThis issue is local to Windows deployments and requires control over values that feed service script generation (for example install-time/runtime arguments or environment-derived values). It can result in unintended command execution in the scheduled task context.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Vulnerable versions: `\u003c= 2026.2.17`\n- Patched version: `\u003e= 2026.2.19` (planned next npm release)\n- Latest published npm version at update time (2026-02-19): `2026.2.17`\n\n### Fix Commit(s)\n- `280c6b117b2f0e24f398e5219048cd4cc3b82396`\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-31994"],"modified":"2026-03-19T21:41:21.015671Z","published":"2026-03-03T21:37:29Z","database_specific":{"cwe_ids":["CWE-116"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-03T21:37:29Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-mqr9-vqhq-3jxw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31994"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/280c6b117b2f0e24f398e5219048cd4cc3b82396"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-local-command-injection-via-unsafe-cmd-argument-handling-in-windows-scheduled-task"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.19"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-mqr9-vqhq-3jxw/GHSA-mqr9-vqhq-3jxw.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
