Lightweight API server for Replicas workspaces

AI Security Review

scanned 27d ago · by lpm-firewall-ai

When the engine runs, every completed agent turn causes its local transcript to be uploaded. The upload includes credential metadata and is sent to a dynamically supplied remote upload URL.

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

Run replicas-engine in a configured workspace and complete an agent chat turn.

Impact

Private chat content and associated credential metadata can leave the workspace without a per-upload user action.

Mechanism

Automatic chat-transcript collection and remote upload.

Attack narrative

The executable starts an engine that invokes uploadChatTranscript after each agent turn. That function reads the local transcript, adds the selected agent credential object to metadata, requests an upload URL from its configured server, and uploads transcript data to the returned location. Separately, its warm-hook service executes supplied hook text with Bash. There is no npm install lifecycle trigger, but the runtime behavior is a concrete automatic data-export capability.

AI rationale

Source inspection confirms automatic upload of agent transcripts and credential metadata to server-directed endpoints during normal runtime. This is concrete data exfiltration behavior, not merely a static scanner match.
