AI Security Review
scanned 4d ago · by lpm-firewall-aiStatic analysis reveals a potentially sensitive credential-forwarding path in source extracted from the packaged executable, but does not establish that the code is reachable or resolve the API recipient. Because the executable analysis is materially limited, the behavior cannot be classified as a confirmed attack or cleared as benign.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A worker starts with localLogins enabled; extracted code indicates this may be enabled by default.
Impact
If reachable, this could disclose third-party account credentials to the configured API recipient; the endpoint host and executable reachability remain unresolved.
Mechanism
The code collects provider access and refresh tokens, then passes credential data as the request body to a local-subscription API.
AI rationale

Decision evidence
public snapshotAI called this Manual Review at 84.0% confidence as Unknown with medium false-positive risk.
AI review observations
- package.json identifies this as the Windows x64 Reason CLI binary package and declares no lifecycle scripts.
- The inspected runtime file contains sandbox path handling for .mcp.json and Claude command and agent directories.
- The offline analysis extracts code that reads OAuth credentials from local agent stores, including access and refresh tokens.
- Extracted code calls a local-subscription API with the credentials as its request body when localLogins is enabled; configuration can default that option to true.
- The offline analysis warns that its bounded source windows do not establish executable reachability or rule out other native behavior.
