Caveat verdict

45
🟠 Risky
Significant risk patterns flagged — automated deep scan, not behavioral proof.

Fetches from network AND uses eval/Function

This security scanner skill (yidun-skill-sec) uploads extracted code snippets from scanned packages to NetEase Yidun's cloud endpoint (as.dun.163.com) enabled by default; while disclosed, sending potentially sensitive code fragments to a third-party service without explicit per-scan consent is a genuine concern.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.

What it does

These are capability combinations: each listed behavior occurs in the skill, but Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.

Capability combination critical

Fetches from network AND uses eval/Function — the remote-code-execution pattern (data-flow not verified)

Capability combination critical

Receives external input AND uses eval — the remote code-injection pattern (data-flow not verified)

LLM01 · LLM05 · ASI01 · ASI05

Capability combination critical

Receives external input AND executes processes — the shape of a command & control channel

Capability combination critical

Encodes data AND uses eval — the obfuscated-execution pattern (atob + eval; data-flow not verified)

LLM05 · ASI05 · ASI10

Capability combination critical

Accesses agent memory/notes AND makes external network calls — may leak personal data

Capability combination critical

Reads files, encodes data, AND makes external network calls — the obfuscated-exfiltration pattern (data-flow not verified)

LLM02 · ASI03

Capability combination high

Reads local files AND makes external network calls — the capabilities for data exfiltration co-occur (data-flow not verified)

LLM02 · LLM06 · ASI03

Capability combination high

Executes processes AND makes external network calls — may exfiltrate command output

LLM02 · LLM06 · ASI03

Capability combination high

Accesses credentials AND makes external network calls — potential credential theft

LLM02 · ASI03

Capability combination high

Accesses credentials AND encodes data — may obfuscate stolen credentials

LLM02 · ASI03 · ASI04

Capability combination high

Accesses agent memory AND makes external network calls — may leak conversation history

Permission integrity

Code accesses API keys/tokens but declares no environment variables
