prozygent@0.8.1

Prozygent - FREE AI Router & Token Saver. Never stop coding. Save 20-40% tokens with RTK + auto-fallback to FREE & cheap AI models.

AI Security Review

scanned 2h ago · by lpm-firewall-ai

The package includes an HTTPS MITM capability for selected AI clients. When enabled, it creates a local CA, proxies traffic, and records request/response data locally. Postinstall also installs pinned SQLite and tray dependencies into the package-owned data directory.

Static reason

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

Trigger

npm postinstall installs runtime dependencies; enabling MITM in the app activates interception and later auto-starts it.

Impact

AI-provider authorization headers, prompts, and responses may be retained locally; no outbound credential exfiltration was confirmed.

Mechanism

local CA-backed AI-client HTTPS interception with local request/response logging

Rationale

The package is not proven malicious: the observed endpoints and proxy behavior align with its stated AI-routing purpose, and no external exfiltration chain was found. It remains a warning because a persistent, CA-backed MITM capability logs potentially sensitive AI traffic and postinstall performs networked runtime dependency installation.
