Security audit

Fetch the latest AI daily brief from imjuya/juya-ai-daily (GitHub) and return the Overview (summary) section.

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims: fetches a public AI daily brief from GitHub and extracts summary text, with no persistence or hidden local changes.

Before installing, confirm you are comfortable with the skill making GitHub requests and optionally using your GitHub token for rate limits. If your token is highly privileged, prefer a low-scope token or leave it unset; also ensure node is available because the metadata only lists curl.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

elif [ -n "${GH_TOKEN:-}" ]; then
    auth=(-H "Authorization: Bearer $GH_TOKEN")
  fi
  curl -fsSL "${auth[@]}" -H "Accept: application/vnd.github+json" "$API" | node -e '
    const fs = require("node:fs");
    const items = JSON.parse(fs.readFileSync(0, "utf8"));
    const candidates = items
Confidence
90% confidence
Finding
Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
