An authorized user may crash the MongoDB server by causing buffer over-read. This can be done by issuing a DDL operation while queries are being issued, under some conditions. This issue affects Mongo
An authorized user can cause a crash in the MongoDB Server through a specially crafted $group query. This vulnerability is related to the incorrect handling of certain accumulator functions when addit
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 a
A user with access to the cluster with a limited set of privilege actions can trigger a crash of a mongod process during the limited and unpredictable window when the cluster is being promoted from a
An authorized user may trigger crashes or receive the contents of buffer over-reads of Server memory by issuing specially crafted requests that construct malformed BSON in the MongoDB Server. This iss
MongoDB Server may be susceptible to stack overflow due to JSON parsing mechanism, where specifically crafted JSON inputs may induce unwarranted levels of recursion, resulting in excessive stack space
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 stems from ins
An unauthorized user may leverage a specially crafted aggregation pipeline to access data without proper authorization due to improper handling of the $mergeCursors stage in MongoDB Server. This may l
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 whet
A use-after-free vulnerability exists in MongoDB Server's server-side JavaScript engine when converting BSON documents to JavaScript arrays. An authenticated user with read privileges who is able to r
An authorized user can issue queries with duplicate _id fields, that leads to unexpected behavior in MongoDB Server, which may result to crash. This issue can only be triggered by authorized users and
MongoDB Server may access non-initialized region of memory leading to unexpected behaviour when zero arguments are called in internal aggregation stage. This issue affected MongoDB Server v6.0 version
MongoDB Server may allow upsert operations retried within a transaction to violate unique index constraints, potentially causing an invariant failure and server crash during commit. This issue may be
After invoking $_internalJsEmit, which is not intended to be directly accessible, or mapreduce command’s map function in a certain way, an authenticated user can subsequently crash mongod when the ser
Stack exhaustion vulnerability in the MongoDB PHP driver can cause application crashes when processing deeply nested BSON documents in unusual circumstances when the source of these BSON documents is
An improper setting of the lsid field on any sharded query can cause a crash in MongoDB routers. This issue occurs when a generic argument (lsid) is provided in a case when it is not applicable. This
When run on commands with certain arguments set, explain may fail to validate these arguments before using them. This can lead to crashes in router servers. This affects MongoDB Server v5.0 prior to 5
A user with access to the cluster with a limited set of privilege actions may be able to terminate queries that are being executed by other users. This may cause a denial of service by preventing a fr
