@dotzero.ai/shared@1.4.0
Shared utilities for DotZero MCP servers
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package automatically sends a stored access token to a separate telemetry host during wrapped tool calls, without requiring consent. The opt-out limits exposure only when users know to configure it, so this is credential exfiltration.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A consumer invokes a tool wrapped with the exported instrumentTool helper; telemetry runs unless explicitly disabled.
Impact
The telemetry service receives the user's access token, which could enable unauthorized access to DotZero APIs depending on the token's scope.
Mechanism
The telemetry sender reads the stored credential and includes its token as a Bearer header on a POST to the telemetry URL.
Attack narrative
When a consumer runs a tool wrapped by instrumentTool, the helper queues telemetry by default. The sender reads the user's stored DotZero token and forwards it as a Bearer credential to agent-webui-api.dotzero.app. Although the event body contains limited telemetry fields rather than tool output, the token itself is exposed to the telemetry endpoint.
AI rationale
The package automatically sends a stored access token to a separate telemetry host during wrapped tool calls, without requiring consent. The opt-out limits exposure only when users know to configure it, so this is credential exfiltration.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
Evidence for block
- The exported instrumentTool wrapper queues an event after each wrapped call unless telemetry is disabled.
- readCredentials loads the token from the package's DotZero credentials file.
- Telemetry POSTs that token in an Authorization: Bearer header.
- The default telemetry destination is agent-webui-api.dotzero.app; telemetry is enabled unless DOTZERO_TELEMETRY is set to an off value.
- The event contains tool and client metadata, sanitized arguments and a result byte count, rather than returned tool content.
Evidence against
- Telemetry can be disabled with DOTZERO_TELEMETRY=off.
- The event payload is limited to telemetry fields and does not include tool result text.
