Affected: OpenClaw

OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in system.run that allows attackers to execute non-allowlisted commands by splitting command substitution using shell line-continuation characters. Attackers can bypass security analysis by injecting $\\ followed by a newline and opening parenthesis inside double quotes, causing the shell to fold the line continuation into executable command substitution that circumvents approval boundaries.

 https://vulnerability.circl.lu/vuln/ghsa-9868-vxmx-w862 GHSA-9868-vxmx-w862 — OpenClaw's system.run allowlist bypass via shell line-continuation command substitution 2026-09-28T19:35:39.945927+00:00

Affected: npm: openclaw

### Summary In OpenClaw `system.run` allowlist mode, shell-wrapper analysis could be bypassed by splitting command substitution as `$\\` + newline + `(` inside double quotes. Analysis treated the payload as allowlisted (for example `/bin/echo`), while shell runtime folded the line continuation into `$(...)` and executed non-allowlisted subcommands.

### Affected Packages / Versions - Package: npm `openclaw` - Latest published affected version: `2026.2.21-2` - Affected range: `<=2026.2.21-2` - Patched version (planned next release): `2026.2.22`

### Impact In deployments that opt into `tools.exec.security=allowlist` (with `ask=on-miss` or `off`), this can bypass approval boundaries and lead to unintended command execution.

### Fix Commit(s) - `3f0b9dbb36c86e308267924c0d3d4a4e1fc4d1e9`

### Remediation - Upgrade to `2026.2.22` (or newer) when published. - Temporary mitigation: set `tools.exec.ask=always` or `tools.exec.security=deny`.

### Release Process Note `patched_versions` is pre-set to planned next release `2026.2.22`. After npm release is out, this advisory should be ready for direct publish without additional metadata edits.
