Summary

The Bg Book Publisher plugin for WordPress up to version 1.25 is vulnerable to Stored Cross-Site Scripting via the 'book_author' post meta rendered through the '[book_author]' shortcode. The plugin fails to properly escape the meta value before output, allowing authenticated attackers with contributor-level access or higher to inject arbitrary web scripts.

Risk Assessment

Malicious scripts can execute in the browser of users visiting affected pages, potentially leading to data theft, session hijacking, or further attacks.

Recommendation

Update the plugin to the latest patched version. If not available, restrict editing of meta fields to trusted users.

Original NVD description (English 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.
