osborn@0.9.204
Voice AI coding assistant - local agent that connects to Osborn frontend
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package exposes runtime data-export and remote-script-execution capabilities with incomplete destination and payload assurance. They are conditionally activated rather than automatic lifecycle behavior, so a warning is proportionate.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A frontend data-channel request for an artifact, or a start_ide command after the CLI starts the agent.
Impact
A configured endpoint can receive selected local artifact contents, and a remote installer can execute with the agent's privileges.
Mechanism
The artifact handler reads approved session/research paths and posts their bytes to a URL built from OSBORN_FRONTEND_URL. The IDE helper invokes a shell command that pipes a remote script to sh.
AI rationale
The package exposes runtime data-export and remote-script-execution capabilities with incomplete destination and payload assurance. They are conditionally activated rather than automatic lifecycle behavior, so a warning is proportionate.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The running agent reads a requested research-artifact file and posts it to an endpoint derived directly from a configurable frontend URL.
- The running agent can download and execute a remote installer through a shell when its IDE-start command is received.
- The package has no npm install lifecycle hook; its only lifecycle script is prepublishOnly.
Evidence against
- The artifact path is restricted to Osborn session/research locations before it is read.
- The remote installer is not automatic: IDE startup is tied to an explicit frontend command.
