Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的"WP Booking System – Booking Calendar"插件在所有 2.1.0.1 及更早版本中存在通用 SQL 注入漏洞。该漏洞源于对用户提供的 参数未进行充分转义，且现有 SQL 查询未进行足够的预处理。这使得拥有管理员及以上权限的已认证攻击者能够将额外的 SQL 查询附加到已有查询中，从而从数据库中窃取敏感信息。 利用该漏洞的前提是目标日历中的预订记录数量超过 200 条，因为 参数仅在 AJAX 处理器进入 分支时才会被传递至数据库层。管理员可通过直接创建预订来满足

Vulnerability Title
WP Booking System <= 2.1.0.1 - Authenticated (Administrator+) SQL Injection via 'orderby' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to generic SQL Injection via the 'data[orderby]' parameter in all versions up to, and including, 2.1.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the targeted calendar to have more than 200 bookings, as the orderby value is only forwarded to the database layer when the AJAX handler takes the use_ajax branch; an Administrator can satisfy this condition by creating bookings directly.
