Security audit

Producer Music

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward AceDataCloud music-generation API guide with expected external API use and no hidden execution or persistence.

Before installing, confirm you trust @acedatacloud and are comfortable sending prompts, lyrics, audio IDs, and reference audio URLs to AceDataCloud. Use a dedicated API key if possible, restrict allowed APIs to the workflows you need, monitor billing, and avoid submitting confidential or rights-sensitive material unless you have approval.

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

Credential Access

High
Category
Privilege Escalation
Confidence
60% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The manifest-style description says to use the skill when creating songs, generating lyrics, extending tracks, creating covers, swapping vocals/instrumentals, replacing sections, or uploading reference audio. This is a wide natural-language activation scope with no explicit trigger phrases, constraints, or negative examples, which could cause unintended invocation for general music-related requests.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill sends prompts, lyrics, and potentially uploaded reference audio to a third-party API, but the setup and workflow docs do not clearly warn users that their content leaves the local environment. In this context, that omission is security-relevant because users may unknowingly transmit copyrighted, confidential, or sensitive audio/text to an external service.

External Transmission

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The manifest description focuses on creating songs, lyrics, covers, edits, swaps, and reference-audio uploads, but the file also documents separate capabilities for stem separation, WAV retrieval, and video generation/download. Those are related to music production, but they are still additional behaviors not reflected in the concise manifest summary.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The setup instructions tell users to include only two allowed API routes, but the rest of the document presents other endpoints like /producer/lyrics, /producer/wav, /producer/videos, and /producer/upload as supported workflows. This is not merely incomplete documentation: it can mislead users into configuring access that contradicts the documented feature set.
