Summary

OpenClaw exec approvals: safeBins could bypass stdin-only constraints via shell expansion

Details

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.

Fix Commit(s)

77b89719d5b7e271f48b6f49e334a8b991468c3b

Release Process Note

patched_versions is pre-set for the next planned release (>= 2026.2.14) so publishing is a single click once that npm version is available.

CVE-2026-28463 (GCVE-0-2026-28463)

Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-04-21 02:43

Title

OpenClaw < 2026.2.14 - Arbitrary File Read via Shell Expansion in Safe Bins Allowlist

Summary

OpenClaw versions prior to 2026.2.14 contain an arbitrary file read vulnerability in the exec-approvals allowlist validation that checks pre-expansion argv tokens but executes using real shell expansion. Attackers with authorization or through prompt-injection attacks can exploit safe binaries like head, tail, or grep with glob patterns or environment variables to disclose files readable by the gateway or node process when host execution is enabled in allowlist mode.

GHSA-XVHF-X56F-2HPP

Vulnerability from github – Published: 2026-02-18 00:50 – Updated: 2026-03-06 01:02

Summary

OpenClaw exec approvals: safeBins could bypass stdin-only constraints via shell expansion

Details

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.

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.

Fix Commit(s)

77b89719d5b7e271f48b6f49e334a8b991468c3b

Release Process Note

patched_versions is pre-set for the next planned release (>= 2026.2.14) so publishing is a single click once that npm version is available.

Thanks @christos-eth for reporting.

  "details": "## Summary\n\nOpenClaw\u0027s 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`.\n\nIn 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 `$HOME/...` without triggering approvals.\n\nThis issue is configuration-dependent and is not exercised by default settings (default `tools.exec.host` is `sandbox`).\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.13`\n- Patched: `\u003e= 2026.2.14` (planned; publish the advisory after the npm release is out)\n\n## Impact\n\nAn authorized but untrusted caller (or prompt-injection) could cause the gateway/node process to disclose files readable by that process when host execution is enabled in allowlist mode.\n\n## Fix\n\nSafe-bins executions now force argv tokens to be treated as literal text at execution time (single-quoted), preventing globbing and `$VARS` expansion from turning \"safe\" tokens into file paths.\n\n## Fix Commit(s)\n\n- 77b89719d5b7e271f48b6f49e334a8b991468c3b\n\n## Release Process Note\n\n`patched_versions` is pre-set for the next planned release (`\u003e= 2026.2.14`) so publishing is a single click once that npm version is available.\n\nThanks @christos-eth for reporting.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
