AI Security Review
scanned 7d ago · by lpm-firewall-aiThe sign-in token is sent to a configurable fileserver API destination, creating conditional credential exposure if an unrelated endpoint is configured. The default same-origin route and user-initiated login do not establish a concrete attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user activates Sign In and completes the registry login flow.
Impact
If the fileserver API base is configured to an unrelated host, the registry token may be exposed to that recipient.
Mechanism
The package places the returned session token in a TOKEN_UPDATED event and POSTs the event to the configured fileserver API base, defaulting to /api.
AI rationale
The sign-in token is sent to a configurable fileserver API destination, creating conditional credential exposure if an unrelated endpoint is configured. The default same-origin route and user-initiated login do not establish a concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- During sign-in, the package obtains a session token from the tscircuit registry and includes it in a TOKEN_UPDATED event.
- The event is sent by POST to the fileserver API base, which uses a configurable window value and defaults to the same-origin /api route.
- The source does not validate that a configured fileserver API base belongs to the registry or to the same origin, leaving conditional exposure if it is set to an unrelated destination.
Evidence against
- The transfer occurs as part of the visible Sign In flow, and the token is issued through the tscircuit registry login exchange.
- The default event destination is the same-origin /api route; source inspection does not establish that an unrelated recipient is configured or that the token was stolen.
