CVE-2025-11867
Bg Book Publisher <= 1.25 - Authenticated (Contributor+) Stored Cross-Site Scripting
The Bg Book Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the book_author post meta, rendered through the [book_author] shortcode, in all versions up to, and including, 1.25.

This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
