WordPress 的 EventON - Subscriber 插件在所有 1.4.5 及更早版本中，因对用户提供的参数缺乏充分的转义处理，且现有 SQL 查询未进行足够的预处理，导致通过"email"参数存在通用 SQL 注入漏洞。这使得未经身份验证的攻击者能够将额外的 SQL 查询附加到现有查询中，从而从数据库中窃取敏感信息。

Vulnerability Title
EventON - Subscriber <= 1.4.5 - Unauthenticated SQL Injection via 'email' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The EventON - Subscriber plugin for WordPress is vulnerable to generic SQL Injection via the 'email' parameter in all versions up to, and including, 1.4.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
