A public media helper can invoke a shell command using an unquoted file path. No automatic malicious install or import-time attack was identified.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

A consumer calls the video-thumbnail helper with a crafted file path.

Impact

An attacker able to control that path could run commands with the consuming application's privileges.

Mechanism

The helper builds an ffmpeg command with template interpolation and passes it to exec, which uses a shell.

AI rationale

The package contains a concrete shell-injection primitive reachable through its exported media functionality. Static inspection did not show malicious lifecycle behavior, so this warrants a warning rather than a publication block.

Summary

Malicious code in @mr-supun-fernando/supunmd-bail (npm)

Details

package.json declares `"libsignal": "github:tenka-san/libsignal-node"` — an off-registry dependency source pointing at a personal-user GitHub repository with no commit SHA, no tag, and no integrity check. On `npm install`, npm clones the current tip of that repository and installs whatever it contains, running any lifecycle scripts (`preinstall`/`install`/`postinstall`/`prepare`) inside the fetched tree on the installer's machine. The dependency key `libsignal` shadows the well-known Signal protocol library, but the source is a personal user's fork rather than the upstream signalapp organization, so whoever controls the tenka-san/libsignal-node repository controls install-time code execution on every installer of this package. The source is mutable — content that resolves benign today can be replaced without any change to this package. A secondary observation: lib/Utils/generics.js line 403 references `ping`, but this is unrelated to the primary install-time execution concern.
