Source shows an automatic runtime path that sends a GitHub credential to the package’s default reporting host without affirmative consent for that recipient. This is credential exfiltration and warrants blocking publication.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A pipeline run reaches the Phase 0 exit gate when a GitHub account is available and registration is needed.

Impact

The reporting service receives a reusable credential for the user’s GitHub account, potentially exposing repositories accessible to that account.

Mechanism

The registration code retrieves a GitHub token and sends it as a bearer credential to the package’s default reporting endpoint.

Attack narrative

During Phase 0, the package automatically invokes usage registration. When a GitHub account is available and registration is needed, the code retrieves that account’s credential and sends it as a bearer credential to the package-selected reporting service. The endpoint’s built-in allowlisting does not provide recipient-specific consent, and the opt-out only helps users who have already enabled it.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The Phase 0 exit instructions invoke usage registration automatically during a run.
Registration obtains a GitHub credential from `gh` or the Git credential helper and passes it as proof to the reporting request.
The default reporting host is `mmerterden.com`; the code permits sending the GitHub credential to that built-in host, and the request uses it as a bearer credential. There is no affirmative recipient-specific consent gate; the opt-out only protects users who have already set it.
Other flagged agent integration locations concern installer paths, plugin status, or the awake helper and do not prevent this credential transfer.

Evidence against

The registration code supports an opt-out and rejects reporting endpoints outside its HTTPS host allowlist, but the package’s default host is allowlisted.

79Severity: Critical. OWASP: M1. Fix effort: High.

81A Swift string literal ends up in the binary's `__TEXT.__cstring` section, where `strings` prints it in seconds. Values in `.xcconfig` files or `Info.plist` ship inside the IPA just the same. The 2025 scan mentioned above found about 78,800 keys for a single cloud provider's APIs alone.

94Secure, in order of preference:

961. A server-side proxy holds the key and the app calls the proxy, so the key never reaches the device.

972. If the device genuinely needs a key, fetch it at runtime from your server after the user or device is authenticated and cache it in the keychain.
