Behavioral Risk Signals
Security Findings1
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Potential Command Injection via unescaped RENDER_API_KEY in curl commands The skill instructs the agent to execute `curl` commands that interpolate the `$RENDER_API_KEY` environment variable directly into the `Authorization` header string. While the variable is enclosed in double quotes, a maliciously crafted `RENDER_API_KEY` containing shell metacharacters (e.g., `"` or `$(...)`) could break out of the string and execute arbitrary commands in the shell environment where the `curl` command is run. This is a common command injection vector when environment variables are not robustly escaped before shell execution. When constructing shell commands, ensure all interpolated variables, especially those from environment or user input, are properly escaped or quoted to prevent shell metacharacters from being interpreted as commands. For `bash`, using `printf %q` to escape the variable before interpolation, or preferably, using a language-specific HTTP client library instead of shelling out, would be safer. If shelling out is necessary, the agent should implement robust escaping for the `RENDER_API_KEY` value. | LLM | SKILL.md:260 |
