Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Shop.app research helper that sends user-directed product or shop queries to Crawlora and does not show hidden persistence, privilege escalation, destructive behavior, or unrelated data access.

Install only if you are comfortable using Crawlora as a third-party API for Shop.app research. Set the API key in CRAWLORA_API_KEY, do not paste secrets or unrelated personal data into search parameters, and expect product/shop queries and public identifiers to be sent to api.crawlora.net.

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

Findings (8)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
92% confidence
Finding

The skill invokes shell commands (scripts/crawlora.sh ...) but does not declare any explicit tool scope or allowed-tools policy. That creates unnecessary ambient authority: a runtime may permit broader shell access than the skill actually needs, increasing the blast radius if the skill is misused or later modified.

External Transmission

Medium
Category
Data Exfiltration
Confidence
89% confidence
Finding

This skill is designed around external network access to api.crawlora.net, so data entered by the user will leave the local environment. That is expected functionality, but it still represents a real security/privacy boundary because prompts, queries, shop handles, product IDs, and possibly behavioral metadata are transmitted to a third party.

Content

Scanner excerpt · reference/endpoints.md (reported line 7)May include surrounding context.

md
Endpoints this skill uses, grouped by platform. 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.

**16 endpoints across 1 platform group(s).**

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The file explicitly instructs use of an external API and an API key header but provides no user-facing disclosure, consent guidance, or handling constraints for outbound data. In a skill that researches products and shops, user queries and derived identifiers may be transmitted off-platform without transparency, creating privacy and credential-handling risk.

External Transmission

Category
Data Exfiltration
Confidence
60% confidence
Finding

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

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

This markdown file says the endpoints are used by the skill and points to another file for calling them, but it does not define any specific activation phrases, boundaries, or negative examples. For a manifest/markdown-scoped trigger review, that leaves invocation scope ambiguous and could contribute to unintended activation if this file is used as descriptive skill metadata.
