Is PageTurn EPUB Reader safe?

Medium risk

PageTurn EPUB Reader runs scripts embedded in user-opened EPUB files inside its reader iframe.

When you open an EPUB, the reader enables JavaScript inside the book content iframe instead of keeping EPUB pages script-disabled. A crafted EPUB can run its own script in that same-origin reader frame while the book is being viewed, affecting data stored or displayed by the reader.
