AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package does not show malicious behavior, but its canvas-clear action deletes all site-origin local storage after a confirmation that describes only clearing the canvas. That broad destructive side effect warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the page builder’s canvas-clear command and accepts its confirmation prompt.
Impact
Other application data stored under the same site origin may also be lost.
Mechanism
After clearing the editor canvas, the component calls localStorage.clear() without limiting the deletion to page-builder data.
AI rationale
The package does not show malicious behavior, but its canvas-clear action deletes all site-origin local storage after a confirmation that describes only clearing the canvas. That broad destructive side effect warrants a warning.
Evidence
fesm2022/inchurch-matcha-components.mjs
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The page builder’s confirmed “clean canvas” action calls localStorage.clear(), deleting every local-storage entry for the site origin.
- The manifest defines no lifecycle scripts; the clearing behavior is in the page-builder component.
Evidence against
- The storage clear runs only after a confirmation prompt, following the user’s canvas-clear action.
- The flagged bidirectional controls appear in Arabic country-name strings, consistent with text direction formatting.
