Vulnerability Title
Find command with $meta sort can lead to crash
Source: CVE Program / CVE List V5
Vulnerability Description
During query planning when reading the sort pattern in raw BSONObj form, in some places we don’t explicitly handle the meta expression case. This may lead to incorrect transformations leading to invariant failure.

MongoDB Server 异常处理不当漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
MongoDB Server是美国MongoDB公司开源的一套开源的NoSQL数据库。该数据库提供面向集合的存储、动态查询、数据复制及自动故障转移等功能。 MongoDB Server 7.0.39之前版本、8.0.28之前版本、8.2.12之前版本和8.3.7之前版本存在异常处理不当漏洞，该漏洞源于在查询规划读取原始BSONObj形式的排序模式时，未显式处理元表达式情况，可能导致不正确的转换，进而导致不变量失败。
