Feed Digest

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently helps summarize RSS/feed content, with disclosed but nonzero risks from installing and using a third-party feed CLI.

Install this only if you trust the feed CLI source and are comfortable with it contacting your configured feed servers and updating your feed read status. Prefer reviewing or pinning the CLI version before installation where possible.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 94% confidence
Finding: The skill description contains broad activation cues such as requests about news, blogs, subscriptions, or 'what's new or interesting today,' which can match many ordinary conversations and cause the skill to trigger when the user did not explicitly ask to use feed data. In an agentic setting, this can lead to unnecessary external data access and actions like fetching feeds or marking entries as read without sufficiently specific user intent.
