Risk Level: HIGHCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
- [PROMPT_INJECTION] (HIGH): The SKILL.md file contains a 'Critical rule' instructing the agent: 'Do NOT read or inspect the script source code. Treat it as a black box.' This is a classic obfuscation technique designed to bypass the AI's ability to reason about its own safety and detect malicious code within the bundled script.
- [COMMAND_EXECUTION] (HIGH): The script executes an external, unverified CLI binary named 'codex'. It uses the '--full-auto' flag by default, which allows the tool to modify files in the workspace autonomously. There is no verification of what this binary does or where it originated.
- [Indirect Prompt Injection] (LOW): The skill is vulnerable to indirect prompt injection because it interpolates untrusted data from the task description and file contents directly into the prompt for the codex tool. Evidence: 1. Ingestion points: --task and --file arguments. 2. Boundary markers: Absent; data is concatenated directly. 3. Capability inventory: Full workspace write access via 'codex exec --full-auto'. 4. Sanitization: Absent; no validation or escaping of input.
