AI Security Review
scanned 4d ago · by lpm-firewall-aiThe flagged code handles an API key submitted through the OAuth connect flow and validates it against the configured OneSource API endpoint. The reviewed entry points and route provide no evidence of automatic credential collection or transmission to an unrelated host.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user submits an API key through the connect-submit route when using the HTTP OAuth flow.
Impact
The reviewed code does not show the key being sent to an unrelated host or collected automatically.
Mechanism
The handler validates the submitted key against the configured OneSource API base URL.
AI rationale
The flagged code handles an API key submitted through the OAuth connect flow and validates it against the configured OneSource API endpoint. The reviewed entry points and route provide no evidence of automatic credential collection or transmission to an unrelated host.
Network endpoints1
api.onesource.io (default; overridable with ONESOURCE_BASE_URL)
Decision evidence
public snapshotAI called this Clean at 92.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest’s package entry is a server factory, and the CLI is a separate executable.
- The flagged handler accepts an API key from an OAuth connect submission and validates it against the configured OneSource API base URL.
- No malicious automatic credential exfiltration or other attack was identified in the reviewed paths.
