Assigner: Wordfence

Description
The WP Hotel Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'widget_search' Shortcode Attribute in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. 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. This is only exploitable on browsers where access keys can be used as the payload is stored in a hidden attribute.

The WP Hotel Booking plugin for WordPress has a stored cross-site scripting (XSS) vulnerability in the 'widget_search' shortcode attribute. This flaw exists in versions up to 2.3.2 due to insufficient input sanitization and output escaping. Attackers with contributor-level access or higher can inject malicious scripts into pages, which execute when users access those pages.

If you use the WP Hotel Booking plugin, an attacker with contributor access could inject malicious scripts into your website. These scripts could steal user data, perform actions on behalf of users, or deface your site. Visitors to your site could have their sessions hijacked or be redirected to malicious sites without their knowledge.

Compliance Impact
