screenpipe CLI — AI that knows everything you've seen, said, or heard

AI Security Review

scanned 12d ago · by lpm-firewall-ai

npm postinstall runs a shell script that can download an unpinned third-party ffmpeg binary into the user home directory, invoke sudo package installs on Linux, and send install analytics to PostHog. The CLI itself only launches the platform binary and reports allowlisted command names.

Static reason

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

Trigger

Automatic npm postinstall after installing screenpipe, when ffmpeg is not already on PATH.

Impact

Install-time fetch and local installation of an unsigned binary plus possible privileged system package changes and hostname analytics, without a checksum pin.

Mechanism

scripts/postinstall.js spawns scripts/postinstall.sh, which curls the latest ffmpeg zip from ffmpeg.martin-riedl.de, installs it under ~/.local/bin, may use sudo package managers, and posts an install event to PostHog.

AI rationale

The postinstall hook visibly installs a screen-recording dependency and sends opt-out analytics, which fits the CLI product, but it still fetches an unpinned third-party binary and can run sudo without a checksum or user prompt. That install-time capability is a real supply-chain risk and is not a proven hidden malware chain.
