Cross-Site Scripting (XSS) in Bg Book Publisher (WordPress plugin) (CVE-2025-11867)
Summary
Cross-site scripting in Bg Book Publisher (WordPress plugin) (CVE-2025-11867). Risk of unauthorized operations or information disclosure. Exploitable via book_author.
Original description
The description as published by the source.
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 is due to the plugin not properly escaping the meta value before output. 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.
