HIGH 7.2

DescriptionCVE.org

The Vagaro Booking Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘vagaro_code’ parameter in all versions up to, and including, 0.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

The Vagaro Booking Widget plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability in the 'vagaro_code' parameter affecting all versions up to and including 0.3. Unauthenticated attackers can inject malicious JavaScript that executes whenever any user visits the compromised page, potentially leading to session hijacking, credential theft, or further site compromise. The CVSS score of 7.2 reflects network-based exploitation with no authentication required and changed scope, indicating the attack can affect resources beyond the vulnerable component.

Technical ContextAI

This vulnerability affects the Vagaro Booking Widget WordPress plugin, identified by CPE cpe:2.3:a:vagaro:vagaro_booking_widget:*:*:*:*:*:*:*:*. The root cause is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), specifically in the handling of the 'vagaro_code' parameter. The plugin fails to implement adequate input sanitization and output escaping on lines 104 and 230 of vagaro-booking-widget.php, allowing raw user input to be stored in the database and rendered directly into HTML output. This is a classic Stored XSS vulnerability where malicious payloads persist in the application's data store and are served to all subsequent visitors, making it more severe than reflected XSS variants.

RemediationAI

WordPress site administrators should immediately update the Vagaro Booking Widget plugin to a version later than 0.3 that addresses this vulnerability, checking for available updates through the WordPress admin dashboard or the official WordPress plugin repository. If no patched version is available or immediate updating is not feasible, administrators should deactivate and remove the plugin until a secure version is released. As an additional hardening measure, implement Web Application Firewall (WAF) rules to filter potential XSS payloads in the 'vagaro_code' parameter and enable Content Security Policy (CSP) headers to mitigate XSS impact by restricting script execution to trusted sources.
