Stored XSS in BA Book Everything WordPress Plugin

Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: Wordfence

Description
The BA Book Everything plugin for WordPress is vulnerable to Stored Cross-Site Scripting via first_name Parameter in all versions up to, and including, 1.8.27 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. An unauthenticated attacker can obtain the valid order_id, order_num, and order_hash credentials required to reach the vulnerable action_to_pay() handler simply by placing a guest booking through the public [babe-booking-form] shortcode, making the full exploit chain reachable without any account.

Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the BA Book Everything WordPress plugin up to version 1.8.27. It occurs due to insufficient input sanitization and output escaping in the first_name parameter. Unauthenticated attackers can inject malicious scripts into pages via a guest booking using the [babe-booking-form] shortcode. The scripts execute when users access the infected page.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the BA Book Everything plugin up to version 1.8.27. Check for suspicious scripts in pages generated via the [babe-booking-form] shortcode. Look for unexpected order_id, order_num, or order_hash values in guest booking forms.

Impact Analysis

An attacker could steal user sessions, redirect users to malicious sites, or perform actions on their behalf. Since no authentication is required, any visitor to an infected page could be affected. The impact includes potential data theft, account compromise, or malware distribution through the injected scripts.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations may face fines or penalties for failing to protect user data from such exploits.

Mitigation Strategies

Immediately update the BA Book Everything plugin to the latest version beyond 1.8.27. If an update is unavailable, consider disabling or removing the plugin until a patch is released. Monitor for unauthorized scripts or guest bookings.
