CVE-2026-27487Network attack vector

Command execution via shell-interpreted OAuth tokens

Published Feb 21, 2026 · Updated Feb 21, 2026

OS command injection in macOS OpenClaw 2026.2.13 and earlier allows remote authenticated users to execute commands through crafted OAuth token data. The Claude CLI keychain refresh path interpolates the updated JSON credential blob into a shell command passed to security add-generic-password, so token metacharacters receive shell interpretation. Exploitation requires control of an OAuth token and user interaction that triggers credential refresh; injected commands run with the OpenClaw user's privileges.
