Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed supplier-research helper that sends user-directed searches and a Crawlora API key to Crawlora, with no evidence of hidden execution, persistence, or local data harvesting.

Install only if you are comfortable sending your Crawlora API key and research queries to Crawlora. Keep the API key in the environment, review query/body contents before running the helper, and pass locale parameters when non-US or non-English search context matters.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

MCP Least Privilege
Confidence
91% confidence
Finding
The skill explicitly instructs the user to run a bundled shell script, but the skill metadata does not declare any tool scope or execution permissions. This creates a trust and review gap: consumers cannot tell from the manifest that shell execution is part of the skill, which increases the chance of unexpected code execution or unsafe script changes being overlooked.

Sudo/Root Execution

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.

Natural-Language Policy Violations

Low
Confidence
88% confidence
Finding
The documentation says Bing search defaults to `country=us` and `lang=en-us`, which imposes a specific locale in natural-language behavior. Because this file does not mention user opt-in or choice around that locale, it can conflict with language/locale policy requirements.
