AI Security Review
scanned 5d ago · by lpm-firewall-aiThe bundle contains an overbroad destructive side effect: confirming a canvas clear also wipes the host application's entire local storage. This is user-triggered and not an install-time or import-time attack, so it warrants a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the editor's canvas-clear command and confirms the prompt.
Impact
Unrelated application state stored under the same origin may be lost.
Mechanism
After clearing the GrapesJS canvas, the command schedules localStorage.clear().
AI rationale
The bundle contains an overbroad destructive side effect: confirming a canvas clear also wipes the host application's entire local storage. This is user-triggered and not an install-time or import-time attack, so it warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The page builder's canvas-clear command calls localStorage.clear(), removing every local storage key for the current origin.
- The clearing runs only after the user invokes canvas-clear and confirms a prompt.
- The manifest has no lifecycle scripts; its package entry is the Angular component bundle.
Evidence against
- The bidi controls found in the bundle appear in Arabic country-name strings, consistent with right-to-left text display.
- The package is a UI component library, and the storage-clearing code is part of its page-builder editor.
