Summary
The @rtk-ai/rtk-rewrite plugin version 1.0.0 fails to sanitize user input before passing it to a shell-backed execSync() template string, allowing arbitrary OS command injection. JSON.stringify() does not protect against shell metacharacters like $() and backticks, which are executed by /bin/sh -c.
Risk Assessment
An attacker who can influence the exec tool's command parameter (e.g., via an LLM agent prompt or gateway/tool-call input) can achieve remote code execution with the privileges of the plugin or gateway process.
Recommendation
Immediately upgrade the @rtk-ai/rtk-rewrite plugin to a version higher than 1.0.0 that includes a fix for shell command injection.
Original NVD description (English source)
@rtk-ai/rtk-rewrite transparently rewrites shell commands executed via OpenClaw's exec tool to their RTK equivalents. In 1.0.0, the @rtk-ai/rtk-rewrite OpenClaw plugin passes attacker-controlled input directly into a shell-backed execSync() template string without shell-safe escaping. JSON.stringify() wraps the value in double quotes and escapes inner double-quotes and backslashes, but leaves $() and backtick shell metacharacters untouched. Because execSync delegates execution to /bin/sh -c, the shell expands $(...) substitutions even inside double-quoted strings, causing the injected subcommand to execute before rtk is invoked. An attacker who can influence the exec tool's command parameter (e.g., via an LLM agent prompt or gateway/tool-call input) achieves arbitrary OS command execution with the privileges of the plugin/gateway process.
