Stock Announcement

Security checks for vulnerabilities and agentic risk

Overview

This skill clearly describes a stock portfolio report that uses Gmail and Sonos, but users should be aware that financial summaries may be emailed and spoken aloud.

Install only if you are comfortable with portfolio information being sent through the configured Gmail account and spoken on the configured Sonos speaker. Use a trusted recipient address, limit who can hear the speaker, and protect the Gmail OAuth token file.

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

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill description states that it delivers a Gmail report and makes a Sonos voice announcement, but it does not clearly warn users that potentially sensitive portfolio information will be transmitted through email and spoken aloud on a network-connected device. This can lead to unintended disclosure of financial information to email recipients, compromised inboxes, people within earshot, or other users on the local network.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The manifest explicitly states that the skill sends a Gmail report and performs a Sonos announcement, which means portfolio-related data may be transmitted to third-party services or broadcast locally without any privacy warning or consent language. In a finance context, even daily portfolio summaries can reveal sensitive holdings and account behavior, so the lack of disclosure increases the risk of unintended data exposure.
