travel-accommodation-research

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed travel-research skill that sends accommodation search data to Crawlora, with no evidence of booking actions, account changes, persistence, or privilege escalation.

Install only if you are comfortable sending travel-search inputs and your Crawlora API key to Crawlora. Keep the key secret, avoid submitting payment data or unrelated personal information, and be aware that Vrbo is supported even though the short manifest description omits it.

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

Tp4

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The manifest describes a limited travel-research skill for Airbnb, Agoda, Hotels.com, and Trip.com, but the body adds VRBO workflows and deeper review/property/rate lookups not disclosed in the declared purpose. This description-behavior mismatch can bypass reviewer and user expectations, causing the skill to access additional data surfaces and perform broader collection than was authorized or understood.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
81% confidence
Finding

The skill invokes shell commands (scripts/crawlora.sh) but does not declare an explicit tool scope such as permissions or allowed-tools. That omission weakens least-privilege controls and makes it easier for a caller or future edit to expand shell-based behavior beyond the intended research workflow without clear policy boundaries.

External Transmission

Medium
Category
Data Exfiltration
Confidence
78% confidence
Finding

This skill is designed around external transmission to api.crawlora.net, so network egress is expected; however, it still represents a real security/privacy boundary because user-supplied travel queries, property identifiers, dates, and related metadata leave the local system. The travel-research context lowers severity because the endpoints are read-oriented and non-transactional, but outbound data flow to a third party should still be disclosed and controlled.

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.

**31 endpoints across 5 platform group(s).**

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The file explicitly instructs use of an API key header for outbound requests but provides no warning about credential sensitivity, transmission to a third-party service, or safe handling expectations. In an agent setting, this increases the risk of unintended secret exposure, unsafe logging, or users being unaware that their queries and identifiers are sent to an external aggregator.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The manifest says the skill compares listings across Airbnb, Agoda, Hotels.com, and Trip.com, but this endpoint reference documents an additional fifth platform, Vrbo. That expands the skill's stated coverage beyond the manifest's described scope, indicating a description-to-behavior mismatch.

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
94% confidence
Finding

The documentation introduces VRBO discovery, quote, and review workflows that are absent from the manifest description, expanding operational scope after the initial declaration. Even if the added behavior remains research-only, undisclosed scope increases the risk of hidden capability creep and reduces the effectiveness of trust and approval processes.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
77% confidence
Finding

This markdown file describes what the skill uses and how to call its endpoints, but it does not provide any explicit trigger phrases, invocation boundaries, or negative examples. In a manifest/markdown context, that omission can make activation conditions overly broad or unclear, increasing the chance of unintended invocation.
