⚠ Under review

It really whips the terminal's ass. A Winamp-shaped audio player for your terminal.

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The inspected source does not substantiate the scanner's claim of an external credential receiver. Several selected runtime dependencies have no available source snapshot, so their behavior remains unresolved and requires review.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Use of settings sync, push notifications, payment handling, or certificate issuance.

Impact

Their behavior remains unverified; the reviewed excerpts do not show credential exfiltration or another confirmed attack.

Mechanism

Those code paths import runtime dependencies whose source was unavailable for inspection.

AI rationale

Evidence

package.jsondist/settings-sync.jsdist/notify.jsdist/paywall.jsdist/certs.js

Decision evidence

public snapshot

AI called this Manual Review at 82.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest lists runtime dependencies whose source was unavailable for this review.
The settings sync module imports the unavailable settings package.
The notification module imports the unavailable push notification package.
The payment and certificate modules import unavailable gateway and ACME packages.
The inspected browser request helper uses same-origin credentials by default and omits cookies for a separate API base; it adds a bearer token only when a session is configured.

Evidence against

The manifest has no install lifecycle hook, and the CLI entrypoint imports the package's main module.
The flagged browser bundle excerpt does not establish a send to an unrelated external receiver.

2 * Any link, played.

4 * Paste a YouTube page, a podcast episode, a SoundCloud track, a TikTok live,

5 * and the server works out where the media actually is and plays it to you

6 * the way it plays a catalog entry: as a channel of its own, started for

7 * whoever asked and stopped a minute after the last viewer leaves. The

8 * working-out is yt-dlp's, which knows a thousand sites and is updated

9 * weekly; this module only asks it the right question and reads the answer.

10 *

11 * Two questions, in fact. "Where is it" is `yt-dlp -j`, one JSON object with

12 * the chosen format's direct URL, its title, and whether it is live. "Give it

13 * to me" is `yt-dlp -o -`, the whole file down a pipe, which is what the

14 * Download button hands to the browser -- the server fetches, the person's

15 * own machine keeps it.

16 *

17 * Some sites want a signed-in cookie before they will say anything (YouTube

18 * from a datacenter, Vimeo). A Netscape cookies file at

19 * ~/.local/state/nixamp/cookies.txt is passed through when it exists, and

20 * the error is otherwise repeated to the person, who can decide.
