Ultimate Flashcards / Podcasts Tutor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward EchoDecks API wrapper whose network use, API key, account mutations, and credit-consuming actions match its stated flashcard and podcast purpose.

Install only if you intend to connect your agent to EchoDecks. Keep ECHODECKS_API_KEY private, expect provided text and study data to be sent to EchoDecks, and be careful with generation commands because they spend account credits. Avoid passing untrusted deck, card, or podcast IDs until the client encodes query parameters safely.

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 Python code file sends user-supplied content and identifiers to a remote API via multiple GET/POST/PUT/DELETE requests, including study data, deck metadata, and freeform text. While the client performs the operations as intended, there is no confirmation prompt, user-facing notice, or explanatory comment/docstring warning that these inputs are transmitted off-system to echodecks.com.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
86% confidence
Finding

The skill requires an API key for an external service but does not warn users that credentials will be transmitted to a third-party API or advise on secure handling. This creates a real, though low-severity, risk of users supplying sensitive credentials without understanding the trust boundary or storage/exposure implications.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill documents AI generation actions that consume account credits, but the warning is incomplete because it notes cost per action without clearly alerting users that executing these tools can cause billable account impact. In an agent context, users may trigger these operations indirectly and incur unwanted charges or resource depletion without meaningful confirmation.
