CVE-2025-11867Bg Book Publisher <= 1.25 - Authenticated (Contributor+) Stored Cross-Site Scripting
Medium 6.4
In plain English
A medium-severity cross-site scripting in Bg Book Publisher from vbog. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 9% of all known vulnerabilities).
Official description
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.
