Bypass of SafeBins Validation in OpenClaw Enables Unauthorized Execution

Publication date: 2026-02-27

Last updated on: 2026-02-27

Assigner: MITRE

Description
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.

Executive Summary

This vulnerability exists in OpenClaw versions before 2026.2.23. It involves the tools.exec.safeBins validation for the 'sort' command, which was intended to restrict execution to approved commands only. However, this validation could be bypassed using GNU long-option abbreviations, such as '--compress-prog', in allowlist mode. Because only the exact string '--compress-program' was denied, these abbreviations allowed execution paths that should have required approval to run without it.

Impact Analysis

The vulnerability can lead to unauthorized execution of commands that were supposed to be restricted or require approval. This can result in an attacker or unauthorized user executing potentially harmful commands without proper authorization, leading to a complete compromise of confidentiality, integrity, and availability of the affected system.
