Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Zalando research helper that sends user-directed product queries to the documented Crawlora API and does not show hidden persistence, privilege escalation, or unrelated data access.

Install this only if you are comfortable sending Zalando search terms, SKUs, markets, and your Crawlora API key to Crawlora. Keep the API key in the environment as documented, do not hardcode it, and review Crawlora/Zalando terms for your intended use.

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

MCP Least Privilege
Confidence
93% confidence
Finding
The skill invokes a shell helper (`scripts/crawlora.sh`) but does not declare any `permissions` or `allowed-tools` scope. That omission weakens least-privilege controls because an agent/runtime may permit broader shell use than is necessary, increasing the blast radius if the skill is misused or later modified.

Privilege Escalation
Content
# Keep the API key out of the curl process command line. A private temporary
# config supplies the header and is removed automatically on exit.
curl_config="$(mktemp "${TMPDIR:-/tmp}/crawlora-curl.XXXXXX")"
chmod 600 "$curl_config"
trap 'rm -f "$curl_config"' EXIT
printf 'header = "x-api-key: %s"\n' "$CRAWLORA_API_KEY" >"$curl_config"
auth=(--config "$curl_config")
Confidence
80% confidence
Finding
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
