Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.80). The skill explicitly fetches and ingests Slack workspace messages, threads, search results and attachments (see SKILL.md canonical workflow and the many
agent-slack message get/listandsearchcommands), which are user-generated third‑party content the agent reads and can drive actions like replies/edits/workflow runs, enabling indirect prompt injection.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill's setup instructs users to run remote code via curl -fsSL https://raw.githubusercontent.com/stablyai/agent-slack/main/install.sh | sh which fetches and immediately executes a script (a required installation step), so the URL is a runtime external dependency that executes remote code.
