AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package is not malicious, but its confirmed canvas-clear action wipes all same-origin local storage. Because this can delete unrelated application data and the editor disables its own storage manager, classify it as a destructive-action risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user selects Clear canvas and confirms the prompt.
Impact
Unrelated same-origin app state, including stored settings or credentials, may be lost.
Mechanism
The handler clears the editor canvas and then calls localStorage.clear() without limiting the deletion to editor data.
AI rationale
The package is not malicious, but its confirmed canvas-clear action wipes all same-origin local storage. Because this can delete unrelated application data and the editor disables its own storage manager, classify it as a destructive-action risk.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The page builder's canvas-clear handler calls localStorage.clear(), removing all local storage for the current origin.
- That broad deletion runs after a confirmation to clear the canvas, so it can remove unrelated app data without happening automatically.
- The editor config sets storageManager: false, so clearing all origin storage is not needed for GrapesJS-managed persistence.
Evidence against
- The package manifest has no install or lifecycle scripts and exposes an Angular component bundle.
- The destructive call is behind an explicit confirmation in the canvas-clear action.
- The bidi controls appear in localized Arabic country names, consistent with right-to-left display rather than concealed code.
