Security audit

Reddit Assistant

Security checks for vulnerabilities and agentic risk

Overview

This Reddit assistant is purpose-aligned, but it tells the agent to run unresolved shell scripts and interpolate user content into Bash commands in a way that could execute unintended commands.

Review this skill before installing. Its Reddit workflows are coherent, and it does not show exfiltration, destructive behavior, or automatic Reddit posting, but it should not run as written unless the referenced scripts are included and audited, commands are invoked without shell interpolation, and users are warned before local product data and analytics logs are saved.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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: 95% confidence
Finding: The trigger phrases are broad enough to match common user requests such as 'reddit content' or 'reddit analytics', which can cause the skill to activate when the user did not intend to invoke it. In a skill that runs shell and Python scripts on startup, unintended invocation increases the chance of unnecessary command execution, file access, and network activity without clear user intent.

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The performance workflow fetches analytics from Reddit and saves updated metrics to local logs, but it does not explicitly warn the user about network access and local persistence. Even though the data is Reddit-related, silent external requests and storage can violate user expectations and organizational policies around outbound access and telemetry retention.
Content: No source excerpt is available for this finding.

Missing User Warnings

Low

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The setup workflow collects product details and writes them to local configuration files, but the instructions do not require informing the user that this data will be persisted. That creates a privacy and consent issue, especially if users provide sensitive business details, URLs, or internal project information assuming the exchange is ephemeral.
