CVE-2026-8063— Post-auth null pointer dereference when aggregating against a view with empty search pipeline

Post-auth null pointer dereference when aggregating against a view with empty search pipeline

An authenticated user can crash mongod when running $rankFusion or $scoreFusion with an empty pipeline on a view. When resolving a view, the server inspects the aggregation pipeline to determine whether it begins with an Atlas Search stage. For $rankFusion and $scoreFusion, this inspection reads the first element on each stage’s input pipeline array without first verifying that the array is non-empty. Supplying an empty pipeline causes a null pointer dereference and crashes the server. This issue affects MongoDB Server 8.2 versions prior to 8.2.7.

空指针解引用

MongoDB Server 代码问题漏洞

MongoDB Server是美国MongoDB公司的一套开源的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 8.2 8.2.7之前版本存在代码问题漏洞，该漏洞源于空管道检查不足，可能导致空指针取消引用并导致服务器崩溃。
