versions:

4.2.0
4.2.1

01/07/2020

When MongoDB recovers from an unclean shutdown, it is possible for the recovery process to corrupt documents that have received size-changing updates.

Affects:

MongoDB Server

3.6.15

09/23/2019

A memory management bug can cause failed operations, process crashes, and in-memory corruption of data that may be persisted to disk.

Affects:

MongoDB Server

versions:

4.2.0

02/22/2018

We have identified a bug in MongoDB Compass where modification or deletion of a document through Compass may occur on a different document than expected under certain specific conditions.

Affects:

Compass

versions:

1.3.x - 1.11.1

05/03/2016

While a background index build is in progress, document updates modifying fields contained in the index specification may, under specific circumstances, cause mismatched index entries to appear. This has an impact on queries that use affected indexes.

Affects:

Indexing

versions:

3.0
3.2

03/30/2016

During chunk migrations, insert and update operations affecting data within a migrating chunk are not reflected to the recipient shard, resulting in data loss.

Affects:

Sharding

versions:

3.0.9
3.0.10

12/16/2015

In a replica set, if a secondary node is shut down cleanly while replicating writes, the node may mark certain replicated operations as successfully applied even though they have not.

Affects:

Replication

versions:

3.2.0

12/09/2015

A race condition in WiredTiger may prevent a write operation from becoming immediately visible to subsequent read operations, which may result in various problems, primarily impacting replication.

Affects:

WiredTiger

versions:

3.0.0 - 3.0.7

06/15/2015

Sharded clusters where the balancer is enabled (or there are manual chunk migrations), containing WiredTiger nodes that may become primary, may lose writes to a chunk being migrated if that chunk is under a heavy write load.

Affects:

Sharding

versions:

3.0.0 - 3.0.3

10/02/2014

MongoDB installations on certain 3.x Linux kernels running on VMWare and using virtual SCSI disks managed by LVM may see corruption in namespace (.ns) files.

Affects:

Storage

versions:

2.4.11
2.6.4

08/03/2014

An update to a text-indexed field may fail to update the text index. As a result, a text search may not match the field contents, yielding incorrect search results.

Affects:

Text Search

versions:

2.4.0 - 2.4.10
2.6.0

01/01/2014

Under very rare circumstances mongos may incorrectly report a write as successful.

Affects:

Sharding

versions:

2.2.0 - 2.2.6
2.4.0 - 2.4.8

10/21/2013

During a chunk migration in a sharded cluster, if one of the documents in the chunk has a size in the range of 16,776,185 and 16,777,216 bytes (inclusive), then some documents may be lost during the migration process

Affects:

Sharding

versions:

2.2.0 - 2.2.5
2.4.0 - 2.4.4

03/21/2013

Secondary indexes (i.e. all indexes other than _id) may be corrupted on an initial sync if write operations are performed on the sync source during the initial sync.

Affects:

Replication

versions:

2.4.0

Operations Related

10/29/2013

Caching of dbhash results may result in stale values, potentially causing disagreement among sharded cluster config servers.

Affects:
