Overseerr

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Overseerr helper, but users should configure it carefully because it can create media requests and sends an API key to the configured server.

Install only if you intend the agent to create and inspect Overseerr requests. Use an HTTPS Overseerr URL for LAN or remote servers, keep the API key narrowly scoped where possible, and prefer searching first or using exact titles when there may be multiple matches.

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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: This script performs a state-changing POST to Overseerr's /request endpoint immediately after selecting the first search result, with no confirmation prompt, dry-run mode, or inline warning. In an agent/tooling context, this can cause unintended media requests from ambiguous titles, prompt injection, or accidental invocation, leading to unauthorized or unwanted changes in the connected media management system.
