TikTok Trend Research

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently supports TikTok trend research by calling a disclosed third-party Crawlora API with a user-provided key, without hidden persistence or unrelated local access.

Before installing, confirm you are comfortable sending TikTok research inputs and your Crawlora API key to Crawlora. Do not include secrets, private customer data, or sensitive personal information in search terms or request fields. Keep the API key in the environment as instructed and rotate it if it may have been exposed.

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

MCP Least Privilege
Confidence
94% confidence
Finding
The skill invokes shell commands and a bundled helper script but does not declare any tool restrictions or allowed-tools scope. That increases the chance an agent can execute shell actions implicitly, making the skill's operational boundary unclear and raising the risk of unintended command execution or secret exposure during use.

External Transmission

Medium
Category
Data Exfiltration
Content
Only the endpoints used by this workflow. Call them via `scripts/crawlora.sh` (see SKILL.md).

All paths are relative to the API base `https://api.crawlora.net/api/v1` and require the header `x-api-key: $CRAWLORA_API_KEY`. Path params like `{id}` are substituted into the URL; `GET` params go in the query string; `POST` params go in a JSON body.

**11 endpoints across 1 platform group(s).**
Confidence
86% confidence
Finding
The skill is explicitly designed to send user-supplied search terms, hashtags, IDs, and other query data to the external service api.crawlora.net using an API key. In this trend-research context that is expected behavior, but it still creates a real data-exposure boundary: any sensitive inputs supplied by a user would leave the local environment and be processed by a third party.

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

Sudo/Root Execution

Category
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.

Missing User Warnings

Low
Confidence
89% confidence
Finding
This markdown file documents calls to an external API and explicitly requires an `x-api-key` header, which implies user or system data may be sent to a third-party service. The file does not include any warning about external transmission, privacy implications, or credential handling.
