BREW-openclaw-cli-CVE-2026-22217 — OpenClaw: shell-env trusted-prefix fallback allowed attacker-controlled binary execution via $SHELL

2026-10-04T00:40:51.310834+00:00

Affected: Homebrew: openclaw-cli

### Summary `shell-env` fallback trusted prefix-based executable paths for `$SHELL`, allowing execution of attacker-controlled binaries in local/runtime-env influence scenarios.

### Details In affected versions, shell selection accepted either: 1. a shell listed in `/etc/shells`, or 2. any executable under hardcoded trusted prefixes (`/bin`, `/usr/bin`, `/usr/local/bin`, `/opt/homebrew/bin`, `/run/current-system/sw/bin`).

The selected shell was then executed as a login shell (`-l -c 'env -0'`) for PATH/environment probing.

On systems where a trusted-prefix directory is writable (for example common Homebrew layouts under `/opt/homebrew/bin`) and runtime `$SHELL` can be influenced, this enabled attacker-controlled binary execution in OpenClaw process context.

The fix removes the trusted-prefix executable fallback and now trusts only shells explicitly registered in `/etc/shells`; otherwise it falls back to `/bin/sh`.

### Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `>= 2026.2.22, <= 2026.2.22-2` - Latest published vulnerable version: `2026.2.22-2` - Patched versions (released): `>= 2026.2.23`

### Fix Commit(s) - `ff10fe8b91670044a6bb0cd85deb736a0ec8fb55`

### Release Process Note This advisory sets `patched_versions` to the released version (`2026.2.23`). This advisory now reflects released fix version `2026.2.23`.

OpenClaw version 2026.2.22 prior to 2026.2.23 contains an arbitrary code execution vulnerability in shell-env that allows attackers to execute attacker-controlled binaries by exploiting trusted-prefix fallback logic for the $SHELL variable. An attacker can influence the $SHELL environment variable on systems with writable trusted-prefix directories such as /opt/homebrew/bin to execute arbitrary binaries in the OpenClaw process context.

WID-SEC-W-2026-0490 — OpenClaw: Mehrere Schwachstellen

2026-10-04T00:40:51.310971+00:00

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren, vertrauliche Informationen offenzulegen, Cross-Site-Scripting-Angriffe durchzuführen, einen Denial-of-Service-Zustand zu verursachen oder andere nicht näher bezeichnete Angriffe durchzuführen.
