Security checks for vulnerabilities and agentic risk

Overview

This is a simple mortgage Q&A skill with broad wording but no code, install hooks, persistence, or hidden access.

Install only if you want general mortgage and credit education. Treat outputs as informational, verify current loan-program and legal details with qualified professionals, and note that the reviewed artifact does not include the underlying knowledge base implementation.

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

Finding

The description says 'Ask anything about the buying process, credit repair, loan programs, or terminology,' which is a very broad activation description for a markdown skill. It does not provide constraints, exclusions, or negative examples to clarify when the skill should or should not be used, increasing the chance of unintended invocation for ordinary conversation about home buying.

Finding

The phrase 'Answer any mortgage or home-buying question instantly' is overly expansive and lacks specificity about eligible topics, excluded requests, or invocation context. For markdown files, this is a vague trigger because it overlaps with common user requests and does not distinguish ordinary chat from skill activation.
