OpenSSF Malicious Packages via OSV

Summary

Malicious code in @alannxd/baileys (npm)

Details

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Independent LPM AI assessment

Suspicious

Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.

This is a concrete command-injection vulnerability in a public helper, but the inspected code does not show automatic exploitation or malicious intent.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A caller supplies a shell-controlled video file path to the public thumbnail utility.

Impact

An application that forwards untrusted paths can allow commands to run with its Node process privileges.

Mechanism

The helper interpolates the path into an ffmpeg command string and passes it to a shell through exec.

AI rationale

This is a concrete command-injection vulnerability in a public helper, but the inspected code does not show automatic exploitation or malicious intent.

Evidence

lib/Utils/index.jslib/Utils/messages-media.js

Independent scan evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Critical Vulnerability with medium false-positive risk.

Evidence for AI warning decision

The public utilities barrel re-exports the media helper module.
The video thumbnail helper builds a shell command by interpolating its file path and invokes it through child_process.exec.
The standard send-media path derives its thumbnail input as an internal original-file path, so exploitation depends on callers passing untrusted paths to the public helper.

Evidence against

No automatic lifecycle path invokes the thumbnail helper with attacker-controlled input.
The inspected ordinary media path uses a package-created temporary file.
