AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package’s purpose and install behavior appear ordinary, but its confirmed canvas-clear action also wipes origin-wide localStorage while editor storage is disabled. That broader deletion could remove unrelated application state, so this warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the page builder’s Clear canvas command and confirms its prompt.
Impact
Other application state saved under the same origin may be lost.
Mechanism
After clearing the editor canvas, the command calls localStorage.clear(); the editor configuration disables GrapesJS storage management.
AI rationale
The package’s purpose and install behavior appear ordinary, but its confirmed canvas-clear action also wipes origin-wide localStorage while editor storage is disabled. That broader deletion could remove unrelated application state, so this warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The manifest exports an Angular browser bundle and declares no install or lifecycle scripts.
- The page builder’s “Clear canvas” command asks for confirmation, then clears all localStorage for the origin.
- The GrapesJS editor sets storageManager to false, so that broad storage wipe is not limited to the editor’s own storage.
- The page builder loads assets from this package’s version-pinned unpkg path in its Angular view lifecycle.
Evidence against
- The manifest lists only tslib as a dependency and has no install scripts.
- The storage wipe requires a user to invoke and confirm the clear-canvas action.
- No credential collection, data exfiltration, or unrelated network collector was identified.
