Stored XSS in BA Book Everything WordPress Plugin

Publication date: 2026-10-02

Last updated on: 2026-10-02

Assigner: Wordfence

Description
The BA Book Everything plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'booking_service_qty' parameter in all versions up to, and including, 1.8.28 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. Successful exploitation requires that an administrator or other privileged user opens the injected order record in the plugin's wp-admin order management area, which is the plugin's ordinary order-review workflow.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the BA Book Everything WordPress plugin. It allows unauthenticated attackers to inject malicious scripts via the 'booking_service_qty' parameter due to poor input sanitization and output escaping. The scripts execute when a privileged user views the infected order record in the plugin's admin area.

Detection Guidance

Check WordPress installations for the BA Book Everything plugin versions up to 1.8.28. Inspect web server logs for unusual script injections in the booking_service_qty parameter. Use security plugins like Wordfence to scan for stored XSS vulnerabilities.

Impact Analysis

An attacker could steal sensitive user session cookies, redirect users to malicious sites, or perform actions on their behalf. If an admin views the infected order, the attacker gains control over the admin's session, potentially leading to full site compromise or data theft.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection principles and HIPAA's security rules. If exploited, it may result in data breaches, triggering compliance violations, fines, or legal consequences for organizations handling protected user information.

Mitigation Strategies

Update the BA Book Everything plugin to the latest version beyond 1.8.28. If an update is unavailable, consider disabling the plugin temporarily. Implement input sanitization for the booking_service_qty parameter and review admin order records for suspicious scripts.
