WordPress 插件 Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots 存在通用 SQL 注入漏洞。该漏洞影响所有版本号不高于 3.0.4 的版本，原因是插件对用户提供的参数 （消息元参数）未进行充分的转义处理，并且在构建现有 SQL 查询时缺乏足够的安全预处理（例如使用预处理语句）。这使得具备订阅者级别或更高级别权限的认证攻击者能够向已有的 SQL 查询中附加额外的 SQL 语句，从而从数据库中提取敏感信息。 利

Vulnerability Title
Better Messages <= 3.0.4 - Authenticated (Subscriber+) SQL Injection via 'group_id' Message Meta Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to generic SQL Injection via 'group_id' Message Meta Parameter in all versions up to, and including, 3.0.4 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 subscriber-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 BuddyBoss Platform plugin to be installed with its Social Groups component disabled, a state that persists on any site that has previously toggled the Groups component off since BuddyBoss does not drop the wp_bp_groups table upon deactivation.
