OpenClaw <2026.2.2 - Command Injection

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-28391. PoCs published by exploitintel.

AI-analyzed exploit summary This repository contains a functional proof-of-concept exploit for CVE-2026-28391, demonstrating a command injection vulnerability in OpenClaw <= 2026.2.1 due to improper handling of Windows cmd.exe parsing behavior. The PoC includes multiple exploit vectors and a Docker-based lab environment for testing.

Description

OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests (non-default configuration), allowing attackers to bypass command approval restrictions. Remote attackers can craft command strings with shell metacharacters like & or %...% to execute unapproved commands beyond the allowlisted operations.
