CVE-2026-28460Public exploitNetwork attack vector

Authenticated command execution via split shell substitution

Published Mar 19, 2026 · Updated Mar 19, 2026

Command injection in OpenClaw before 2026.2.22 allows remote authenticated users to execute non-allowlisted commands through system.run. The allowlist analyzer accepts a dollar sign, backslash-newline, and opening parenthesis inside double quotes, while the shell folds them into executable command substitution. Exposure requires tools.exec.security=allowlist with ask set to on-miss or off, allowing commands to cross the configured approval boundary.
