A specially crafted aggregation query with $lookup by an authenticated user with write privileges can cause a double-free or use-after-free memory issue in the slot-based execution (SBE) engine when an in-memory hash table is spilled to disk.

A use-after-free vulnerability can be triggered in sharded clusters by an authenticated user with the read role who issues a specially crafted $lookup or $graphLookup aggregation pipeline.

An authenticated user with the read role may read limited amounts of uninitialized stack memory via specially-crafted issuances of the filemd5 command.

An authorized user may disable the MongoDB server by issuing a query against a collection that contains an invalid compound wildcard index.

MongoDB Server may experience an out-of-memory failure while evaluating expressions that produce deeply nested documents. The issue arises in recursive functions because the server does not periodically check the depth of the expression.

Complex queries can cause excessive memory usage in MongoDB Query Planner resulting in an Out-Of-Memory Crash.

Incorrect validation of the profile command may result in the determination that a request altering the 'filter' is read-only.

An authorized user may trigger a server crash by running a $geoNear pipeline with certain invalid index hints.
