AI Security Review
scanned 5d ago · by lpm-firewall-aiThe editor requires a user action and confirmation, but that confirmation only describes clearing the canvas while the code clears all origin-wide localStorage. This overbroad data deletion is a real risk, though the source does not show it happening automatically or maliciously.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user selects the editor’s “Limpar tudo” command and confirms the canvas-clear prompt.
Impact
Other application data stored under the same origin, such as preferences or session state, may be lost.
Mechanism
After clearing the editor canvas, the command calls localStorage.clear() without restricting deletion to editor keys.
AI rationale
The editor requires a user action and confirmation, but that confirmation only describes clearing the canvas while the code clears all origin-wide localStorage. This overbroad data deletion is a real risk, though the source does not show it happening automatically or maliciously.
Evidence
fesm2022/inchurch-matcha-components.mjsAll localStorage keys for the current browser origin
Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- After the user confirms clearing the canvas, the command calls localStorage.clear(), removing all localStorage keys for the current origin.
- GrapesJS storageManager is disabled, so the operation is not limited to editor-managed storage.
- The command is exposed as an editor option labeled “Limpar tudo” (“Clear all”).
Evidence against
- The storage clear requires a user to choose the canvas-clear command and confirm; it does not run on install or import.
- The manifest has no lifecycle scripts and exports the component bundle as the package entry point.
