Security checks for vulnerabilities and agentic risk

Overview

This skill provides read-only entertainment research through a disclosed service, with a few extra public-data lookups beyond movies and TV.

Use a dedicated Crawlora key and keep queries free of private information: the service receives them, and calls may consume credits. The reference also includes game research and public Letterboxd profile statistics. The supplied files show no material security concern; the remote service itself was not audited.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The declared scope is movies and television, but the executable route allowlist explicitly enables video-game research. These routes are an undeclared capability, even though they use the same API provider. The API-key handling, temporary curl configuration, and GET request implementation are supporting details and do not independently constitute mismatches.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: shell.

Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

- Get a free Crawlora API key (2,000 credits/mo, no card) at [<redacted-url>).
- Set `CRAWLORA_API_KEY` in the environment before running the helper.
- The helper reads `CRAWLORA_API_KEY` from the environment and sends requests to `https://api.crawlora.net/api/v1`. Missing/invalid key → `401`.

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.

args=()

Letterboxd member-profile statistics introduce user-account research unrelated to title research (L403–L407).

Excessive Agency
Confidence
93% confidence
Finding

This endpoint accepts an arbitrary username and retrieves account-level statistics, including films watched, lists, and follower/following counts. Although the information is public, researching audience accounts is distinct from retrieving a title's metadata, cast, ratings, reviews, streaming offers, or box-office performance.

Content

No source excerpt is available for this finding.

The skill's endpoint reference includes video-game metadata and review capabilities outside its movie/TV research purpose (L611–L627).

Category
Excessive Agency
Confidence
98% confidence
Finding

The file identifies these as endpoints the skill uses (L005), including dedicated Metacritic game-detail, game critic-review, and game user-review endpoints. Researching video games is a distinct capability not justified by the manifest's movie and TV scope; naming Metacritic as a source does not declare support for all its content categories.

Content

No source excerpt is available for this finding.

The route allowlist permits video-game research outside the movie and TV research scope.

Low
Category
Excessive Agency
Confidence
99% confidence
Finding

L177–L179 explicitly allow Metacritic game metadata, critic-review, and user-review routes, which the helper can request using the Crawlora API key. Video-game research is not justified by the manifest's stated movie and TV research purpose.
