Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward AI news digest helper that searches current web sources and can optionally save a markdown newsletter when requested.

Install this if you want an agent to browse current AI news and produce concise digests. Use inline output if you do not want files created, and choose file output only when you are comfortable with a dated newsletter being written under the outputs directory.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The invocation guidance says to use this skill whenever a user asks for AI news, wants a roundup, asks what happened today or this week, or even says follow-ups like 'more AI news' or 'catch me up on AI.' These broad phrases overlap with ordinary conversational requests and explicitly expand activation even when the user does not ask for a newsletter, increasing the risk of unintended invocation.

Autonomous Decision Making

Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Missing User Warnings

Confidence
84% confidence
Finding

The skill instructs the agent to write a file into user storage and present it, but it does not require an explicit confirmation or warning before creating the file. While the path appears constrained and the filename is date-based, silent file creation can still surprise users, create clutter, or overwrite prior outputs if rerun on the same date.
