Vulnerability in Openclaw
CVE-2026-100584
OpenClaw is an npm-distributed agent runtime. In versions >= 2026.2.26 and < 2026.7.1, PowerShell command analysis on Windows hosts running in exec allowlist mode could approve an exact executable resolved from PATH but subsequently execute a same-named executable located in the workspace directory. If lower-trust content can place an executable with an approved basename into an agent-writable workspace and steer an approved PowerShell command that uses a bare executable name, OpenClaw may run the workspace file instead of the allowlisted path, executing arbitrary code with the privileges of the Gateway or node-host user. The issue does not require replacement of the approved executable itself. Version 2026.7.1 contains a fix; as a workaround, avoid bare executable names in approved PowerShell commands and keep executable files out of agent-writable workspaces.
