Summary

The HotelRunner Booking Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'hotelrunner' shortcode in all versions up to, and including, 5.2.4 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.

Risk Assessment

An attacker with contributor-level access can persistently inject malicious script that executes when a user visits the infected page, potentially leading to data theft or session hijacking. This impacts the confidentiality and integrity of user data.

Recommendation

Update the HotelRunner Booking Widget plugin to a version newer than 5.2.4 as soon as it becomes available. Until then, consider limiting its use or implementing additional XSS protections.
