{"id":"CVE-2026-31994","aliases":["GHSA-mqr9-vqhq-3jxw"],"url":"https://o3.security/vulnerability/CVE-2026-31994","summary":"OpenClaw < 2026.2.19 - Local Command Injection via Unsafe cmd Argument Handling in Windows Scheduled Task Script Generation","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: `<= 2026.2.17`\n- Patched version: `>= 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.","published":"2026-03-19T01:00:52.737Z","modified":"2026-08-12T03:51:29.366922334Z","cvss":null,"epss":{"score":0.00571,"percentile":0.44653,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.19"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/280c6b117b2f0e24f398e5219048cd4cc3b82396","label":"openclaw/openclaw@280c6b1"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31994.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-local-command-injection-via-unsafe-cmd-argument-handling-in-windows-scheduled-task"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/280c6b117b2f0e24f398e5219048cd4cc3b82396"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.366922334Z"}}
