Mongodb: >> Mongodb >> 8.2.3 Security Vulnerabilities
A use-after-free vulnerability exists in MongoDB's Field-Level Encryption (FLE) query analysis component, affecting client-side uses of mongocryptd and crypt_shared. Triggering this vulnerability requires control over the structure of a client's FLE-related query.
This issue impacts MongoDB Server’s mongocryptd component v7.0 versions prior to 7.0.34, v8.0 versions prior to 8.0.23, v8.2 versions prior to 8.2.9 and v8.3 versions prior to 8.3.2.

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.
