AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The source contains a concrete externally triggerable remote installer execution path, but no npm install-time hook or evidence that the package uses it as covert malware. Treat it as a critical vulnerability requiring a publish warning.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Start the agent service, then send GET /editor while code-server is absent.

Impact

A remote server response is executed with the privileges of the agent process.

Mechanism

The route calls the IDE startup hook, which runs curl against code-server.dev and pipes the response to sh.

AI rationale

Evidence

dist/index.js

Network endpoints1

code-server.dev/install.sh

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Critical Vulnerability with low false-positive risk.

Evidence for warning

The HTTP /editor route has no authentication gate and invokes the IDE startup hook.
IDE startup downloads an external installer and pipes it directly to sh when code-server is absent.
The package has no registry install lifecycle hook; its only lifecycle script is prepublishOnly.

Evidence against

The risky download occurs only after the agent's HTTP service is running and /editor is requested.
The observed behavior is an exposed remote-code-execution vulnerability, not evidence of a covert install-time payload.
