AI Security Review

scanned 2d ago · by lpm-firewall-ai

The source confirms conditional forwarding of an account token to a configurable server URL without a fixed recipient restriction, so a warning is appropriate. The saved-server workflow and explicit URL registration are product-aligned and do not establish malicious intent.

Static reason

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

Trigger

Opening the radio page while signed in causes it to select the remembered server or the first listed server and load it.

Impact

That server receives the account token; a recipient that accepts it may be able to act with the account’s access.

Mechanism

The page fetches the account token from its same-origin endpoint and uses it as a bearer credential for requests to the selected server URL.

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The radio page retrieves a signed-in account token and the account’s server list, then automatically selects the remembered server or the first listed server.
Requests to a selected server use the account token as a bearer credential and omit same-origin cookies.
The source accepts HTTP or HTTPS server addresses without binding the token to a fixed recipient; the CLI allows a caller to register a URL.
The server list is intended for the user’s own servers, and the CLI’s add command accepts an explicit URL, which limits evidence of malicious intent.

Evidence against

The token is obtained from the same-origin account endpoint and the recipient comes from the account’s saved server list, rather than a hardcoded publisher destination.
No install lifecycle hook is declared in the manifest. The observed behavior is part of the browser server-management feature.
