AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing this package can silently add a separate global AI-agent executable. The action occurs before the user invokes this package's CLI.

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

npm installation runs the postinstall lifecycle hook when no supported AI agent is detected.

Impact

It mutates the user's global AI-agent environment and introduces a separately maintained executable without explicit installation consent.

Mechanism

Postinstall execution invokes a global npm installation of opencode-ai.

Policy narrative

On npm install, package.json runs scripts/postinstall.js. That script calls ensureDefaultKernel, which checks for installed AI runners and, if none are found, executes npm install -g opencode-ai. This is an automatic lifecycle-time global installation of a separate AI agent rather than package-local setup or a user-invoked command.

Rationale

The package performs an unconsented postinstall mutation of a broad, foreign AI-agent control surface by globally installing opencode-ai. This concrete lifecycle behavior warrants blocking even though no secret exfiltration was found.
