Risk Level: HIGHCOMMAND_EXECUTIONDATA_EXFILTRATIONPROMPT_INJECTION
Full Analysis
- [COMMAND_EXECUTION]: The skill provides instructions for the agent to execute shell commands, including
opencodeCLI calls for model execution andcurlfor interacting with a local API server. It also uses a one-line Python script to parse JSON responses. - [DATA_EXFILTRATION]: The skill includes instructions to perform network operations against
http://localhost:4096. These requests are used for connectivity heartbeats and API interaction with a local service. Localhost is a whitelisted domain, and no external data exfiltration was detected. - [PROMPT_INJECTION]: The skill presents an indirect prompt injection surface by instructing the agent to interpolate
{constructed_prompt}(which may contain untrusted data from external sources) into shell command arguments or API request bodies. - Ingestion points: The
{constructed_prompt}variable is interpolated intoopencode runcommands and HTTP POST payloads inSKILL.md. - Boundary markers: No explicit boundary markers or 'ignore' instructions for the interpolated content are defined in these reference files.
- Capability inventory: The skill utilizes subprocess execution and local network access.
- Sanitization: There is no evidence of input validation or sanitization for the interpolated data within the skill's instructions.
Recommendations
- HIGH: Downloads and executes remote code from: http://localhost:4096 - DO NOT USE without thorough review
