Allowlist Bypass in OpenClaw exec safeBins Enables Arbitrary File Write

Publication date: 2026-03-19

Last updated on: 2026-03-25

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.19 contain an allowlist bypass vulnerability in the exec safeBins policy that allows attackers to write arbitrary files using short-option payloads. Attackers can bypass argument validation by attaching short options like -o to whitelisted binaries, enabling unauthorized file-write operations that should be denied by safeBins checks.

Executive Summary

This vulnerability exists in OpenClaw versions prior to 2026.2.19 and involves an allowlist bypass in the exec safeBins policy. Attackers can exploit this by using short-option payloads, such as attaching the -o option to whitelisted binaries, to bypass argument validation. This allows them to write arbitrary files, performing unauthorized file-write operations that the safeBins checks are supposed to prevent.

Impact Analysis

The impact of this vulnerability is that an attacker with low privileges can write arbitrary files on the system by bypassing the safeBins policy. This unauthorized file-write capability can lead to integrity issues, potentially allowing the attacker to modify or place malicious files, which can compromise the system's security and stability.
