CVE-2026-55249Public exploitNetwork attack vector

OS command execution via execSync template interpolation

Published Jun 23, 2026 · Updated Jun 23, 2026

OS command injection in RTK AI Labs @rtk-ai/rtk-rewrite 1.0.0 allows remote authenticated users to execute commands via exec tool input. The OpenClaw before_tool_call hook interpolates the command parameter into an execSync() shell template after JSON.stringify(), leaving $() and backticks active. An attacker must influence an exec tool call while the default-enabled plugin is loaded; injected commands run with the OpenClaw gateway process privileges.
