CyberRota Analysis
AI-GeneratedThe Hostel plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping of user-supplied shortcode attributes, specifically in the 'wphostel-book' shortcode. This vulnerability allows authenticated attackers with Contributor-level access and higher to inject malicious scripts into web pages, which can execute when other users access those pages. WordPress site administrators using this plugin should prioritize patching or updating to mitigate potential exploitation risks.
Original NVD Description
The Hostel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wphostel-book' shortcode in all versions up to and including 1.1.7. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the second shortcode attribute (used as button text) is passed to the `$text` variable without sanitization at line 79 and then output directly into an HTML `value` attribute at line 91 without `esc_attr()` or any other 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.
