AI Security Review
scanned 5d ago · by lpm-firewall-aiThe clear-canvas action has an overbroad destructive side effect: confirmation to clear the editor also clears all origin-wide local storage. This is a real data-loss risk, though it requires an explicit user action, so the package is suspicious rather than malicious.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes Clear canvas and confirms the prompt.
Impact
Other application data in local storage may be lost.
Mechanism
After clearing the editor canvas, the command calls localStorage.clear() without limiting deletion to editor data.
AI rationale
The clear-canvas action has an overbroad destructive side effect: confirmation to clear the editor also clears all origin-wide local storage. This is a real data-loss risk, though it requires an explicit user action, so the package is suspicious rather than malicious.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The page builder’s confirmed “clean the canvas” action also calls localStorage.clear(), which erases all local storage for the site origin.
Evidence against
- The storage deletion runs only after the user invokes the canvas-clear command and confirms it.
- The package is an Angular component library; its manifest exports the bundled component entry point.
- The page builder loads version-pinned assets from the package’s own unpkg URL.
