AI Security Review
scanned 5d ago · by lpm-firewall-aiThe confirmed canvas-clear action also wipes the embedding site's entire localStorage, creating a destructive side effect beyond the user's stated action. This is a warning-level concern because the wipe requires an explicit confirmation and no malicious collection or transmission was identified.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user selects clear canvas and accepts the confirmation prompt in MatchaPageBuilder.
Impact
Other application state stored for the same site, potentially including session or preference data, is also deleted.
Mechanism
After clearing the GrapesJS canvas, the code calls localStorage.clear().
AI rationale
The confirmed canvas-clear action also wipes the embedding site's entire localStorage, creating a destructive side effect beyond the user's stated action. This is a warning-level concern because the wipe requires an explicit confirmation and no malicious collection or transmission was identified.
Evidence
fesm2022/inchurch-matcha-components.mjs
Decision evidence
public snapshotAI called this Suspicious at 96.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The page builder asks for confirmation before clearing its canvas, then calls localStorage.clear(), which removes every local storage key for the embedding site.
- The clear behavior is part of the browser-based page-builder component, whose initialization runs in ngAfterViewInit.
Evidence against
- The manifest declares no lifecycle scripts.
- The storage wipe requires a user to confirm the canvas-clear action; no credential collection or external data transfer was identified.
