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:
- a shell listed in
/etc/shells, or - 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
