Vulnerability from github – Published: 2026-02-27 06:31 – Updated: 2026-02-28 02:17

Summary

OpenClaw is vulnerable to validation bypass through GNU long-option abbreviations in allowlist mode

Details

In OpenClaw before 2026.2.23, tools.exec.safeBins validation for sort could be bypassed via GNU long-option abbreviations (such as --compress-prog) in allowlist mode, leading to approval-free execution paths that were intended to require approval. Only an exact string such as --compress-program was denied.

Severity

9.9 (Critical)

Summary

OpenClaw's tools.exec.safeBins sort long-option abbreviation bypass can skip exec approval in allowlist mode

Details

Summary

In OpenClaw, tools.exec.safeBins validation for sort could be bypassed via GNU long-option abbreviations in allowlist mode, allowing approval-free execution paths that should require approval.

Affected Packages / Versions

Ecosystem: npm
Package: openclaw
Latest published version checked: 2026.2.22-2
Affected range: <= 2026.2.22-2
Fixed version: 2026.2.23

Impact

When all of the following are true: - tools.exec.security=allowlist - tools.exec.ask=on-miss - tools.exec.safeBins includes sort

abbreviated GNU long options (for example --compress-prog) could bypass denied-flag checks and be treated as allowlist-satisfied safe-bin usage, skipping approval.

Root Cause

Long-option handling matched denied flags by exact string and accepted unknown long options with inline values instead of failing closed.

Fix Commit(s)

Release Process Note

patched_versions is pre-set to the released version (2026.2.23). This advisory now reflects released fix version 2026.2.23.

OpenClaw thanks @tdjackey for reporting.
