Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward AI-news newsletter generator that uses web search and fetching as expected, with no hidden execution, persistence, or local data access.

Install this skill if you want a Simplified Chinese AI-news newsletter and are comfortable providing Brave and Firecrawl API keys for web search and page fetching. Review provider privacy terms if search queries or fetched URLs are sensitive.

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 (2)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The description explicitly requires the newsletter and summaries to be returned in Simplified Chinese for a Chinese audience. This is a language-policy constraint stated as mandatory behavior, and the file does not provide an option for the user to choose another language or opt in to this locale restriction.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The language output section instructs the skill to always return the newsletter body and summaries in Simplified Chinese. Because no alternative language selection or opt-in is offered, this violates the language/locale policy criterion.
Content: No source excerpt is available for this finding.
