AI Security Review
scanned 5d ago · by lpm-firewall-aiThe clear-canvas command performs an origin-wide local-storage wipe after a confirmation that describes only clearing the canvas. This is a potentially destructive, unexpectedly broad side effect, so I recommend a warning rather than treating the package as malicious.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the canvas-clear command and confirms the prompt.
Impact
Unrelated application data stored under the same origin may be lost.
Mechanism
After clearing the GrapesJS canvas, the component calls localStorage.clear() without limiting deletion to page-builder data.
AI rationale
The clear-canvas command performs an origin-wide local-storage wipe after a confirmation that describes only clearing the canvas. This is a potentially destructive, unexpectedly broad side effect, so I recommend a warning rather than treating the package as malicious.
Evidence
fesm2022/inchurch-matcha-components.mjsBrowser origin localStorage (all keys)
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- After a generic “clean the canvas” confirmation, the page builder clears the canvas and calls localStorage.clear(), which removes every local-storage key for the current origin.
- The manifest identifies an Angular ESM component library and declares no lifecycle scripts.
- The flagged bidi controls appear in Arabic country-name labels in a data table, consistent with localization data.
- The bundle loads GrapesJS assets for its page-builder component.
Evidence against
- The local-storage wipe is triggered only after a user confirms the canvas-clear action.
- No install-time lifecycle script is declared in package.json.
- The bidi controls occur in localized country labels rather than concealed executable code.
