Summary

OpenClaw's exec-approvals allowlist supports a small set of "safe bins" intended to be stdin-only (no positional file arguments) when running tools.exec.host=gateway|node with security=allowlist.
In affected configurations, the allowlist validation checked pre-expansion argv tokens, but execution used a real shell (sh -c) which expands globs and environment variables. This allowed safe bins like head, tail, or grep to read arbitrary local files via tokens such as * or $HOME/... without triggering approvals.
This issue is configuration-dependent and is not exercised by default settings (default tools.exec.host is sandbox).

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected: <= 2026.2.13
  • Patched: >= 2026.2.14 (planned; publish the advisory after the npm release is out)

Impact

An authorized but untrusted caller (or prompt-injection) could cause the gateway/node process to disclose files readable by that process when host execution is enabled in allowlist mode.

Fix

Safe-bins executions now force argv tokens to be treated as literal text at execution time (single-quoted), preventing globbing and $VARS expansion from turning "safe" tokens into file paths.
