• Severity: medium (CVSS 6.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-10-22 · updated 2026-10-08
• Weakness: CWE-79

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.
