WordPress 的 Readabler 插件在所有低于 2.0.18 版本（不含 2.0.18）中存在 SQL 注入漏洞，原因是未对用户提供的参数进行充分的转义处理，且现有 SQL 查询语句缺乏足够的预处理措施。这使得未经身份验证的攻击者能够在已存在的查询语句中追加额外的 SQL 查询，从而从数据库中提取敏感信息。

Readabler < 2.0.18 - Unauthenticated SQL Injection

Vulnerability Description
The Readabler plugin for WordPress is vulnerable to SQL Injection in all versions up to 2.0.18 (exclusive) 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.
