Summary
OpenClaw: shell-env trusted-prefix fallback allowed attacker-controlled binary execution via $SHELL
Details

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.
