Security audit

sentisense

Security checks for vulnerabilities and agentic risk

Overview

This is a read-only SentiSense financial data skill that uses an API key to query SentiSense endpoints and does not show hidden execution, persistence, trading, or destructive behavior.

Install only if you are comfortable giving SentiSense an API key-backed record of the market data requests you make, including tickers, searches, watchlists, and screener filters. Treat outputs as informational market data, not investment advice, and do not use it as a trading or order-execution tool.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

The section 'What You Can Build' introduces broad use cases without any explicit trigger phrases, invocation boundaries, or exclusion conditions for when the skill should or should not be used. In a skill markdown file, this kind of open-ended capability description can lead an agent platform to invoke the skill for generic finance-related requests beyond the author's intended scope.

Vague Triggers

Confidence

Finding

The getting-started instruction encourages immediate use but does not specify the kinds of user requests that should trigger this skill. In a markdown skill description, such generic wording can contribute to ambiguous activation behavior if the host uses natural-language descriptions for routing.
