AI Security Review
scanned 2d ago · by lpm-firewall-aiThe source allows an operator-configured API destination and sends the existing bearer token to it, creating conditional credential exposure. The default destination is Cachly’s API, so the inspected behavior supports a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
The operator configures CACHLY_API_URL or --api-url to a custom destination, and the server makes an authenticated request or encounters one of the telemetry-triggering failures.
Impact
A custom destination can receive a token associated with the Cachly account and may be able to use it to access that account.
Mechanism
The shared request helper sends the bearer token to the selected API URL, and failure telemetry requests attach the same token in an Authorization header.
AI rationale
The source allows an operator-configured API destination and sends the existing bearer token to it, creating conditional credential exposure. The default destination is Cachly’s API, so the inspected behavior supports a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The server defaults to Cachly’s API, but CACHLY_API_URL or the --api-url option can select another destination.
- The shared API request helper and two failure telemetry requests attach the existing bearer token to requests sent to the selected API destination.
- The autopilot command reads a token from CACHLY_JWT; the flagged runtime locations are tool handler operations, not automatic account changes.
- The cache, brain, context, team, roadmap, syndicate, and fedbrain excerpts show tool-driven data handling and response formatting.
Evidence against
- The default API destination is https://api.cachly.dev, and the inspected source does not establish a hidden publisher-selected recipient for the token.
- Token exposure to another destination depends on the operator configuring a custom API URL; the source does not show that this is enabled by default.
