What is CVE-2026-1838?

The Hostel plugin for WordPress has a vulnerability that allows for Reflected Cross-Site Scripting (XSS) through the 'shortcode_id' parameter. This issue arises from inadequate input sanitization and output escaping, enabling unauthenticated attackers to inject malicious scripts. If a user is deceived into clicking on a compromised link, these scripts can execute within their browser session, potentially leading to unauthorized actions or data exposure.
