CVE-2026-1607: Surbma | Booking.com Shortcode

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

The Surbma | Booking.com Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `surbma-bookingcom` shortcode in all versions up to, and including, 2.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
