Kaspa News

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Kaspa news reader that fetches public kaspa.news data and formats it for users, with no evidence of credential use, persistence, or destructive behavior.

Install this if you are comfortable with the agent making public network requests to kaspa.news and presenting cached social/news content. Be aware that the trigger guidance is broad, so ambiguous mentions of kaspa.news could activate the skill; use explicit requests when you want it to fetch current Kaspa data.

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

Findings (3)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
87% confidence
Finding

The skill requires internet access to query a remote API but declares no explicit tool scope or allowed-tools/permissions boundary. In agent environments, undeclared network capability weakens policy enforcement and can let the skill be invoked with broader access than reviewers or operators expect.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger phrase guidance is overly broad, especially the catch-all activation on 'Any mention of kaspa.news'. Broad triggers can cause the skill to activate in contexts where the user did not intend external fetching, increasing the chance of unnecessary network access, incorrect routing, or prompt-surface expansion from untrusted remote content.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
