Hum: a self-improving coding agent for your terminal.

AI Security Review

scanned 8d ago · by lpm-firewall-ai

The CLI can send its saved Hum bearer token to a URL selected by HUM_AUTH_URL or the saved auth URL, without restricting the destination to Hum’s service. Because sending is conditional on pending health events and the default destination is Hum’s service, this warrants a warning for credential exposure, not a block.

Static reason

One or more suspicious static signals were detected.

Trigger

A CLI run reaches a reporting call while pending health events exist, such as an install, core, or startup failure.

Impact

A configured destination outside Hum’s service could receive the saved access token and diagnostic data.

Mechanism

The report selects HUM_AUTH_URL, then the saved auth URL, then Hum’s service as its destination; it adds the saved token as a bearer authorization header.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The CLI reads a saved credential and lets HUM_AUTH_URL or the saved auth URL select the health-report destination.
It can attach the saved access token as a bearer token to a POST request.
Reports include system details and diagnostic information, and the CLI invokes reporting during command runs and session startup.
Sending requires pending health events; the report destination is not restricted to Hum’s service.

Evidence against

Reports are conditional on pending install, core, or startup events, and the default destination is Hum’s service.
