music-video

Security checks for vulnerabilities and agentic risk

Overview

The skill is a disclosed music-video workflow that uses an Ofox API key for paid visual generation while keeping the user's audio local for final muxing.

Before installing, confirm you are comfortable providing an Ofox API key, paying for generated video segments after an explicit cost table, and installing the separate ofox-video-core dependency if it is missing. Review any npx install command yourself before running it, and use an absolute output directory so generated files do not land inside the skill folder.

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

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Sudo/Root Execution

Medium
Category
Privilege Escalation
Content
```

Missing on macOS: `brew install ffmpeg`; Debian/Ubuntu:
`sudo apt-get install ffmpeg`. Both binaries come from the same package.
Find this out **now** rather than after the segments are paid for — `chain`
refuses to start a multi-shot run without `ffmpeg` for exactly that reason,
and a piece with its audio still missing is not the thing the user asked for.
Confidence
70% confidence
Finding
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Unbounded Output

Output Handling
Content
<SCENE: where it is, the light source and its direction, the foreground layer>

<0-3s>   <shot size>, <camera position>, <movement or "static">. <one action>. <what the light does>
<3-6s>   <Hard cut. | Without cutting,> <shot size>, ... 
<6-9s>   ...
<...>    ...
<T-2 - T s>  <the closing picture — this is what the next segment opens on, so make it a picture worth continuing from>
Confidence
60% confidence
Finding
Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.
