Risk Level: HIGHREMOTE_CODE_EXECUTIONEXTERNAL_DOWNLOADSPROMPT_INJECTIONSAFE
Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill provides a command to update itself by fetching and executing a shell script (
install.sh) from the vendor's official GitHub repository. As this resource is provided by the identified author 'Canner', it represents standard vendor functionality. - [EXTERNAL_DOWNLOADS]: The skill performs a network request to the vendor's GitHub repository to retrieve version information (
versions.json) for update checking purposes. - [PROMPT_INJECTION]: The skill ingests untrusted data from an external database to build manifests, presenting an indirect prompt injection surface.
- Ingestion points: Metadata is ingested via the
list_remote_tables()andlist_remote_constraints()tools as described inSKILL.md. - Boundary markers: No explicit delimiters or instructions are used to separate the ingested metadata from the agent's instructions during the MDL construction process.
- Capability inventory: The skill has the capability to deploy manifests and perform dry runs via
deploy_manifest()anddry_run()tools. - Sanitization: There is no mention of sanitizing or escaping column/table names or constraints before they are interpolated into the manifest structure.
- [SAFE]: Sensitive database credentials are never handled directly by the skill prompts or the ibis-server API; instead, users are directed to manage connections through a local Web UI or a local JSON file.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/Canner/wren-engine/main/skills/install.sh - DO NOT USE without thorough review
