AI Security Review

scanned 22d ago · by lpm-firewall-ai

Static source inspection establishes conditional credential forwarding to an unrestricted configured destination, warranting a warning. No concrete malicious behavior or automatic install attack was identified.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Run an authenticated workflow or development command with an alternative server selected through options or workspace configuration.

Impact

An alternative server can receive the user's Tapi ID token.

Mechanism

The CLI loads cached credentials and sends the ID token as bearer authorization without restricting the destination to its intended service.

Decision evidence

public snapshot

AI called this Suspicious at 96.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

dist/auth.js reads an existing Tapi ID token from its credential cache.
dist/cli.js supplies cached Firebase credentials to user-invoked workflow commands.
dist/workflow-cli.js combines cached credentials with a configurable server; dist/dev-context.js applies no destination allowlist.
dist/client.js sends the token as bearer authorization to the selected server.
Studio development also forwards cached credentials through runner enrollment to the configured server.
package.json contains no automatic install lifecycle hooks.

Evidence against

Credential forwarding requires a user-invoked command and a configured alternative destination.
The default server is used consistently by Tapi features; no hidden unrelated recipient was identified.
Inspected process execution supports workflow and development commands.
