WordPress 的 Comments 插件在 7.6.66 版本之前，由于未对用于构建数据库查询的输入值进行充分验证，导致未认证用户可以注入 SQL，从而读取他们本无权查看的评论。这些评论包括：等待审核的评论、被标记为垃圾或已移至回收站的评论，以及位于私有或草稿文章下的评论。 所注入的文本是以语法结构（而非数据）的形式进入查询语句，因此无法提取任意数据，保密性影响仅限于被披露的评论内容本身，而不涉及整个数据库。

Vulnerability Title
Comments – wpDiscuz < 7.6.66 - Unauthenticated Comment Disclosure via SQLi
Source: CVE Program / CVE List V5
Vulnerability Description
The Comments WordPress plugin before 7.6.66 does not validate a value used to build a database query, allowing unauthenticated users to inject SQL and read comments they are not entitled to see, including comments awaiting moderation, comments marked as spam or trashed, and comments on private and draft posts. The injected text reaches the query as grammar rather than as data and does not yield extraction of arbitrary data, so the confidentiality impact is the disclosed comment content rather than the database at large.
