Unofficial Facebook Chat API for Node.js - Interact with Facebook Messenger programmatically

AI Security Review

scanned 6d ago · by lpm-firewall-ai

User-supplied or fca-config.json Facebook credentials are transmitted to a hard-coded third-party server. This occurs during normal email/password login or automatic session recovery.

Static reason

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

Trigger

Call login with email/password, or invoke login with configured credentials when auto-login recovery runs.

Impact

Third party can capture Facebook credentials, 2FA codes, and returned session cookies/tokens.

Mechanism

Hard-coded credential forwarding to a remote login API.

Attack narrative

The package’s normal credential-login path sends email, password, and optional two-factor code to a hard-coded external host rather than directly to Facebook. The same path is used by automatic recovery when credentials are present in fca-config.json; the response may include Facebook cookies and access tokens. This is concrete credential and session-material exfiltration triggered by ordinary package use.

Rationale

Source inspection confirms a default third-party endpoint receives credentials on the normal login and auto-login paths. Documentation acknowledges an external API but does not remove the concrete default credential-exfiltration risk.
