Affected: Homebrew: openclaw-cli

### Summary In the macOS companion app (**currently beta**), a parsing mismatch in exec approvals could let shell-chain payloads pass allowlist checks in `system.run` under specific settings.

### Impact This path requires all of the following: - authenticated caller with `operator.write` - paired macOS beta node host - exec approvals set to `security=allowlist` and `ask=on-miss`

Under those conditions, a shell-chain command could be approved from an incomplete command view and then executed on the paired macOS host.

### Default Install Status Default installs are not affected.

### Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.21-2` - Patched (planned next release): `>= 2026.2.22`

### Technical Details The fix hardens macOS allowlist resolution by evaluating shell chains per segment and failing closed on unsafe shell-substitution parsing in allowlist mode.

### Product Status Note The affected macOS companion app path is currently in beta.

### Fix Commit(s) - `5da03e622119fa012285cdb590fcf4264c965cb5` - `e371da38aab99521c4e076cd3d95fd775e00b784`

### Release Process Note `patched_versions` is pre-set to the planned next npm release (`2026.2.22`) so once that version is published, this advisory can be published without additional metadata edits.

OpenClaw thanks @tdjackey for reporting.

Affected: OpenClaw

OpenClaw versions prior to 2026.2.22 contain an allowlist parsing mismatch vulnerability in the macOS companion app that allows authenticated operators to bypass exec approval checks. Attackers with operator.write privileges and a paired macOS beta node can craft shell-chain payloads that pass incomplete allowlist validation and execute arbitrary commands on the paired host.
