Reason CLI native binary for linux-x64-musl
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe executable’s embedded source establishes an automatic runtime transfer of saved third-party access tokens to the Reason service, with local login sharing enabled by default. This is concrete credential disclosure and supports blocking publication.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Connecting the CLI with its default local-login setting enabled starts the worker transfer.
Impact
Saved third-party service tokens are disclosed to the Reason service without a separate recipient-specific consent gate in this transfer path.
Mechanism
The worker reads local agent credential stores, retains provider access tokens, and submits them in authenticated local-subscription requests.
Attack narrative
When the CLI worker runs with local logins enabled, it reads saved OAuth credentials from local agent stores and periodically submits provider access tokens through the authenticated local-subscription endpoint. The connection configuration defaults this feature on. The inspected source does not establish a separate consent gate for sending those third-party tokens to the Reason service.
AI rationale
The executable’s embedded source establishes an automatic runtime transfer of saved third-party access tokens to the Reason service, with local login sharing enabled by default. This is concrete credential disclosure and supports blocking publication.
Evidence
.lpm-inspection-14EdJ3/0-dd636e964ba2.txt
Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- The executable reads OAuth credentials from local agent credential files and keychain storage.
- A recurring worker task sends collected provider access tokens to the authenticated local-subscription endpoint.
- The connection configuration enables local logins by default, and the worker starts the transfer when that setting is enabled.
Evidence against
- The manifest has no lifecycle scripts; the transfer is a runtime behavior of the CLI.
