Caveat verdict

brave-shim

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

Receives external input AND executes processes

The skill uses a Python script to locate and overwrite OpenClaw's bundled JavaScript files (brave-web-search-provider*.js) to redirect Brave API endpoints to a local service, directly modifying the host application's installed code — unusual and broad capability well beyond its stated search-proxying purpose.

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

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

LLM05 · LLM06 · ASI10

Capability combination critical

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

Enumerates directory contents AND makes external network calls — filesystem reconnaissance

LLM02 · LLM06 · ASI03

Capability combination high

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

LLM02 · LLM06 · ASI03

Capability combination high

Installs packages AND executes processes — opaque dependency chain with execution

LLM03 · ASI04

Permission integrity

Makes network requests but does not declare curl/wget in required binaries

network_out

Installs packages at runtime — transitive dependencies are not auditable

package_install

Findings (4)

Pattern match high

HTTP request to bare IP address — common in malicious payloads

SKILL.md · code · http://127.0.0.1

Pattern match medium

subprocess execution — runs system commands from Python

scripts/setup_brave_shim.py · prose · downgraded · subprocess.run(

Pattern match medium

subprocess with shell=True — command injection vector

scripts/setup_brave_shim.py · prose · downgraded · subprocess.run(cmd, shell=True

Pattern match low

Python directory traversal

Why the tier is capped

Execution sink present in raw bytes (Hard Floor: class D/F). Final tier capped at Caution — cannot be lifted by any downgrade, example-payload opt-in, or allowlist.

Permissions & capabilities

No declared permissions — minimal attack surface.
