Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent public-news research helper that calls a disclosed third-party API and does not show hidden persistence, privilege escalation, destructive behavior, or private-data access.

Install only if you are comfortable sending news queries, article URLs, and your Crawlora API key to Crawlora. Avoid putting secrets, private personal data, or confidential research topics in query parameters, and be aware that the skill can also retrieve public TV-news metadata and Yahoo reader comments, not just article headlines.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
90% confidence
Finding

The skill invokes shell commands in its examples (scripts/crawlora.sh ...) but does not declare any tool scope such as permissions or allowed-tools. That creates an authorization gap where an agent may execute shell access more broadly than intended, especially if user-controlled query values are later interpolated into commands or if reviewers cannot tell that code execution is required.

External Transmission

Medium
Category
Data Exfiltration
Confidence
86% confidence
Finding

This skill is designed to transmit user-supplied queries and fetched URLs to api.crawlora.net, an external service. External transmission is expected for the skill's function, but it remains security-relevant because it can expose user research topics, sensitive prompts, or linked content to a third party if not clearly disclosed and constrained.

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.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The manifest says the skill builds news briefings from GDELT, BBC, CNN, The Guardian, and Yahoo News, suggesting recent news-source research. The endpoint reference shows extensive GDELT TV capabilities over US television captions, transcripts, OCR text, concept entities, and visual labels, which is a materially broader media-analysis surface than ordinary source-aware news briefings from the named outlets.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The manifest describes a skill for building source-aware news briefings from headlines, topic monitoring, source comparison, and coverage timelines with links, dates, and uncertainty preserved. The documented Yahoo endpoints include article comment and reply harvesting, which is a distinct user-generated-content collection capability not implied by that briefing/research description.

External Transmission

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.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

The documentation instructs use of an external API key and remote service without any warning about credential handling, data disclosure, or safe transmission practices. In an agent setting, this can lead users or downstream tooling to send sensitive queries or mishandle secrets when invoking the external service.
