medium 6.4 CVE-2026-6910 · published 2026-07-09

Stored cross-site scripting (XSS) in Bookero.pl (2.2 and older)

Affected: 2.2 and older
Fixed in: unknown
Access needed (per CVSS): Needs a low-level account (e.g. subscriber)
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Bookero.pl – system rezerwacji online plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `bookero_products` shortcode's `hide_products` (and `filter_products`) attributes in versions up to and including 2.2. This is due to insufficient input sanitization and output escaping in the `bookero_products()` function — the raw attribute value is concatenated directly into an inline `<script>` block without any escaping. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts into pages that will execute whenever a user accesses the injected page.
