What our analysis found

Beautiful Epub Reader, used by 40,000 people, is rated caution by Extension Auditor. Our code review reported 1 finding (1 high), led by other. It comes from a trusted publisher and was last updated in July 2026.

Key findings

  • High

    Other

    The bundled manifest includes host permission for [domain withheld], but the published CWS listing summary shows only file://*. This discrepancy may indicate that the extension has access to a sensitive domain not disclosed to users in the store listing.

Analyst notes

Manifest mismatch between bundled version and published CWS summary (missing [domain withheld] host permission). DeclarativeNetRequest permission is unusual for an epub reader, and publisher's other extensions are flagged malicious, but no source code was provided to confirm malicious behavior. Limited analysis without JavaScript files.
