AI Security Review

scanned 23d ago · by lpm-firewall-ai

The active development path forwards an existing service credential to an unrestricted configurable destination, meeting the credential-forwarding warning rule. No separate concrete malicious behavior supports publication blocking.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Run tapi studio dev with a custom server option or a workspace configuration selecting another server.

Impact

An operator of the selected server could receive the user's Tapi ID token.

Mechanism

Cached Tapi credentials are refreshed and passed to runner enrollment, which sends the ID token in an Authorization header without a destination allowlist.

Decision evidence

public snapshot

AI called this Suspicious at 97.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The auth module reads the existing Tapi ID token and refresh token from its credential cache.
Studio development refreshes cached credentials and passes them to runner enrollment.
The development server can be supplied through command options or inherited from workspace configuration.
Server normalization removes trailing slashes without restricting the destination host.
Runner enrollment sends the cached ID token as a bearer credential to the selected server.
The CLI activates this behavior through the Studio development command.

Evidence against

No registry-install lifecycle hook or runtime self-dependency appears in package.json.
The default server is the Tapi backend; exposure requires a different configured destination.
Inspected process launches support explicitly invoked development and workflow operations; no covert recipient or malware intent was established.
