Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill's documentation in
SKILL.mdinstructs the user to install the Codex CLI by downloading and executing a shell script directly from a well-known service's domain (curl -fsSL https://chatgpt.com/codex/install.sh | sh). - [COMMAND_EXECUTION]: The skill generates commands using
codex execthat include a high-risk flag-s danger-full-access. This indicates that the executed commands operate with significant privileges or broad system access. - [PRIVILEGE_ESCALATION]: By explicitly instructing the agent to use the
danger-full-accessscope, the skill seeks to bypass standard restrictions and acquire elevated permissions within the execution environment. - [EXTERNAL_DOWNLOADS]: The skill references the installation of an external Node.js package (
@openai/codex) and a Homebrew cask (codex) to provide its core functionality. - [INDIRECT_PROMPT_INJECTION]: The skill processes external files and user-provided instructions, creating a surface for potential injection attacks where malicious data could influence the generated commands.
- Ingestion points: In
SKILL.md, the 'Document → Diagram' mode reads local files from<INPUT_PATH>and incorporates them into the instruction set along with<USER_INSTRUCTIONS>. - Boundary markers: None are present; the content of the files is interpolated directly into the command string.
- Capability inventory: The skill uses the
codexCLI to execute instructions and interacts with the file system to save generated images. - Sanitization: There is no evidence of input validation, escaping, or filtering for the data read from external files before it is passed to the shell.
Recommendations
- HIGH: Downloads and executes remote code from: https://chatgpt.com/codex/install.sh - DO NOT USE without thorough review
