AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package is not clearly malicious, but its confirmed clear-canvas action also erases all origin local storage. Since the prompt does not disclose that broader deletion, warn users about this destructive behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user activates Clear canvas in the editor and confirms the prompt.
Impact
Other application data saved in that origin’s local storage may be lost.
Mechanism
After clearing the canvas, the handler calls localStorage.clear() without limiting deletion to editor data.
AI rationale
The package is not clearly malicious, but its confirmed clear-canvas action also erases all origin local storage. Since the prompt does not disclose that broader deletion, warn users about this destructive behavior.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The editor’s clear-canvas command asks for confirmation, clears the canvas, then calls localStorage.clear(), which removes all local storage for the origin.
- The editor loads its scripts from unpkg.com in ngAfterViewInit when the editor component is used; this is not install-time execution.
- The flagged bidi characters appear in a country-name string for Afghanistan, consistent with localized text.
Evidence against
- The manifest declares no lifecycle scripts.
- The broad storage deletion is behind a confirmation prompt, though the prompt refers only to clearing the canvas.
