Vulnerabilities

A vulnerability in MongoDB Server's BSON validation logic allows an unauthenticated user to crash the mongod process by sending a specially crafted message.

The $_internalApplyOplogUpdate aggregation pipeline stage can be used to execute a document diff containing a malformed binary diff to return memory out-of-bounds or crash the server.

An authorized user could trigger a server crash by running a query with a 2dsphere index on a field that stores a GeoJSON GeometryCollection containing a Polygon with a strict-winding CRS.

The ldapQueryPassword parameter, when set through the runtime setParameter command, will log the new password to the mongod.log file in plain text.

An authenticated user can cause a MongoDB server to crash or return incorrect results by creating documents that interfere with internal metadata processing during query execution.

This issue can occur when running an aggregation pipeline that uses the internal $exchange stage configured with key-range partitioning and order-preserving delivery.

Adding fromRouter:true and runtimeConstants.userRoles could cause aggregations to crash mongodb server.

When using $changestreams and $_requestReshardingResumeToken with the exchange option the server hits an invariant which causes the server to crash.
