Channel Manager worker daemon — runs on remote machines to execute video pipeline jobs

AI Security Review

scanned 8d ago · by lpm-firewall-ai

The cache route forwards worker-authenticated data to unauthenticated local callers and allows cross-origin reads. This is a real security risk, but the inspected source does not establish active malicious behavior or the scope of data exposed, so a warning is appropriate.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The user runs the daemon while a web page can make requests to the local cache server.

Impact

A web page that can reach the loopback service may read data available through the worker's cache resolver; the source does not establish what data a caller can obtain.

Mechanism

The route accepts a file key, uses the worker token to fetch data from the dashboard API, and returns it with wildcard CORS.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Critical Vulnerability with medium false-positive risk.

Evidence for warning

The CLI starts the daemon, which starts the local cache server.
The cache server binds to 127.0.0.1:8849 and listens for requests there.
A GET to /cache/s3 accepts a file key without an authentication check and returns the resolved data.
The response allows reads from any web origin with wildcard CORS.
The cache server uses the worker token to fetch the requested data from the dashboard API.

Evidence against

The server binds to loopback, limiting direct access to the local machine.
