AI Security Review
scanned 4d ago · by lpm-firewall-aiThe bundle automatically loads BloomLibrary analytics and reports book metadata and reading activity without a clear disclosure in the package manifest. This is suspicious runtime telemetry, but the inspected code does not show credential theft or unrelated data collection.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
When the player starts and when a book is opened or reading activity is reported; analytics is skipped only when the URL contains `independent=false`.
Impact
BloomLibrary analytics receives details about the book and the reader's activity. No credential or local file collection was identified.
Mechanism
The bundle loads BloomLibrary's analytics script and tracks book-open and reading events with book metadata and progress metrics.
AI rationale
The bundle automatically loads BloomLibrary analytics and reports book metadata and reading activity without a clear disclosure in the package manifest. This is suspicious runtime telemetry, but the inspected code does not show credential theft or unrelated data collection.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package is a Bloom book display library, and the bundle loads analytics by default unless the URL contains `independent=false`.
- Production analytics code loads from `https://bloomlibrary.org/analytics.min.js`.
- On book open, the player tracks an event with book metadata including title, creator, publisher, book instance ID and session ID.
- The player records reading progress metrics such as pages read, audio and video duration, and reading duration.
Evidence against
- The manifest has no lifecycle scripts, and the exported module is a browser library for displaying books.
- The bidi-like characters found in the bundle are left-to-right marks in multilingual language-name data; no bidi control characters were found.
