Title
Race Condition in MongoDB Server Document Value Layer Leads to Memory Corruption
Summary
A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.

Title
Integer Overflow in Query Planner Leads to Unbounded Memory Allocation and Denial of Service in MongoDB Server
Summary
An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.

Title
Uncontrolled Resource Consumption in MongoDB Sharded Cluster Router Allows Unauthenticated Denial of Service
Summary
An uncontrolled resource consumption weakness exists in the request-handling path of the MongoDB sharded-cluster router process. A client that has network access to a router port and has not authenticated can supply connection-monitoring parameters that cause the server to expend CPU resources without any rate limiting, degrading or denying service to legitimate clients. No authentication, elevated privileges, or user interaction is required. Only availability is affected; data confidentiality and integrity are not impacted.

Title
Improper Validation in MongoDB Server Aggregation Framework Allows Authorization Bypass and Unauthorized Collection Access with Atlas Search
Summary
A security issue in the MongoDB Server aggregation framework allows an authenticated user with limited read privileges to bypass view-level authorization checks and access data from unauthorized collections when Atlas Search features are in use. The issue stems from insufficient validation of an internal command parameter that can be set by external clients, causing a security check to be improperly skipped.

Title
Insufficient Validation of Storage Engine Configuration Options in MongoDB Server Leads to Out-of-Bounds Write
Summary
Insufficient validation of storage engine configuration options in MongoDB Server allows an authenticated user with write privileges to supply crafted parameters during collection creation that override internal storage metadata. This results in an out-of-bounds memory write in the server process, causing a denial of service via server crash, with potential for further impact including arbitrary code execution.

Title
Insufficiently Protected Credentials in MongoDB Server Diagnostic Reporting Interface
Summary
A security issue in MongoDB Server's diagnostic reporting interface allows an authenticated user with monitoring privileges to access insufficiently protected credentials from concurrent administrative operations. The same credentials are properly redacted in server log output, but the diagnostic interface omits equivalent redaction. Successful exploitation requires a valid authenticated session with monitoring-level permissions and results in exposure of cleartext credentials that could enable impersonation of other users, including privileged accounts.

Title
Improper Redaction of Query Literals in MongoDB Server Query Statistics Serialization on Sharded Cluster Router
Summary
A security issue in MongoDB Server's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypassed when processing search queries through the sharded cluster router. This results in sensitive query literals being stored and made accessible through the query statistics interface.

Title
Persistent Fatal Assertion Crash in MongoDB Server via Crafted Retryable Write Commands Leads to Denial of Service
Summary
A security issue in MongoDB Server allows an authenticated user with write privileges to trigger a persistent fatal assertion crash by sending specially crafted retryable write commands. The crash state is durably persisted, causing the server process to repeatedly crash on restart and potentially propagating to additional nodes in a sharded cluster. Manual intervention is required to restore service availability.

Improper Case Sensitivity Handling in MongoDB Server Configuration Validation May Cause Authorization to Remain Disabled at Startup
Summary
Improper handling of case sensitivity in the configuration validation component of MongoDB Server may cause the authorization subsystem to remain in a default disabled state during server startup. An unauthenticated user with network access to a deployment where this condition occurs can perform arbitrary administrative operations, resulting in full impact of data confidentiality, integrity, and availability.

Title
Heap Out-of-Bounds Read in MongoDB Server Query Planning Component
Summary
A heap out-of-bounds read security issue exists in the query planning component of MongoDB Server. An authenticated user with database read and write privileges can trigger the security issue through crafted query operations, causing the server to read memory beyond allocated buffer boundaries. The revealed memory contents may be partially observable through diagnostic query statistics output.

Title
Insufficient Validation of Storage Configuration Options in MongoDB Server Leads to Persistent Denial of Service via Corrupted Metadata
Summary
A security issue in the MongoDB Server's storage engine integration layer allows an authenticated user with collection creation privileges to cause a persistent denial of service. Insufficient validation of user-supplied storage configuration options permits values that, once persisted to durable metadata, trigger a fatal assertion failure when the metadata is subsequently read by diagnostic operations. The corrupted metadata persists across server restarts and is replicated to other cluster members, requiring manual operator intervention to restore service.

Title
Unauthenticated Denial of Service in MongoDB Server via Assertion Failure in Read Concern Processing on Replica Set Members
Summary
A security issue in MongoDB Server allows an unauthenticated network user to cause a denial of service on a specific type of replica set member. The server contains an assertion in its read concern processing logic that can be reached without authentication, and the assertion's assumptions about internal state do not hold for all member configurations, causing the server process to terminate.

Title
Use-After-Free in MongoDB Server Cursor Management Component Leads to Denial of Service
Summary
A use-after-free security issue in the cursor management component of MongoDB Server allows an authenticated user to cause a denial of service. Under specific timing conditions during cursor operations, a stale pointer to a freed resource may be retained and subsequently dereferenced during cursor cleanup, leading to a server process crash.

Title
Improper Authorization in MongoDB Server applyOps Command Allows Writes to Arbitrary Internal Storage Tables via Feature Gate Bypass
Summary
A security issue in MongoDB Server allows an authenticated user with elevated internal privileges to bypass a disabled feature gate in the applyOps command by specifying an internal replication mode value that was not intended to be client-selectable. This bypass enables execution of container operations that are disabled by default in production configurations, allowing direct storage-engine writes to arbitrary internal storage tables. The authorization check for these operations validates only the operation's namespace, not the actual storage target, enabling writes to unrelated internal metadata or other collections' data.

Title
Insufficient Validation of Shard Key Values in MongoDB Server Leads to Query Operator Injection in Change Stream Post-Image Lookups
Summary
In MongoDB, insufficient validation of shard key values during document insertion allowed authenticated users to store documents with specially crafted, operator-shaped objects as shard key values in sharded collections. When change stream events for such documents were processed with the updateLookup full document mode, the crafted values were embedded into internal post-image lookup queries without proper sanitization, causing them to be interpreted as query operators rather than literal equality values. This could result in change stream consumers receiving incorrect post-image documents or encountering non-resumable fatal errors.

Title
Improper Access Restriction of Internal Aggregation Expression in MongoDB Server Leads to Assertion Failure and Denial of Service
Summary
An internal aggregation expression in MongoDB Server was incorrectly registered as accessible to any authenticated user rather than being restricted to internal cluster operations. By crafting a malformed index specification within this expression, an authenticated user with read-only privileges could trigger an assertion failure in the index key generation code path. In certain build configurations, this assertion failure results in termination of the mongod process, causing a denial of service to all connected clients.

Title
Unhandled Exception in MongoDB Server JSON Schema Validation Error Generation Leads to Denial of Service
Summary
A flaw in MongoDB's JSON Schema validation error generation code allows an authenticated user with readWrite privileges to crash the mongod server. When a BSON document containing an array with a malformed numeric field name fails a $jsonSchema items type constraint, the error generation path performs unsafe numeric conversion on the user-controlled field name without proper exception handling, resulting in an uncaught exception that terminates the server process. This is possible because incoming wire protocol BSON validation does not enforce that array element field names are valid, in-range numeric indices.

Title
Type Confusion in MongoDB Server WiredTiger Storage Engine via Custom Collection Configuration Leads to Persistent Denial of Service
Summary
A security issue was discovered in MongoDB where an authenticated user with readWrite privileges could crash the mongod server process. By specifying a custom WiredTiger storage configuration option with an incompatible value during collection creation, a user could cause a type confusion in the storage engine layer. When documents were subsequently read from the misconfigured collection, the resulting mismatch in expected data format led to corrupted memory interpretation and a server crash. The crafted collection configuration persists across restarts, requiring manual operator intervention to remediate.

Title
Race Condition in MongoDB Server Text Index Query Parsing Leads to Heap Use-After-Free and Denial of Service
Summary
A race condition in MongoDB server's text index query parsing can cause a heap use-after-free read when handling upsert retry paths. Under certain concurrent index lifecycle operations, a raw pointer to internal text index metadata may be dereferenced after the underlying structures have been freed, leading to a server crash. An authenticated user with readWrite privileges can trigger this condition through specific concurrent text-search and index management operations, resulting in denial of service for all connected clients.

Title
Null Pointer Dereference in MongoDB Server 2dsphere Index Key Generation Leads to Denial of Service
Summary
A security issue exists in MongoDB's 2dsphere index key generation that can cause a server crash due to a null pointer dereference. When a specially crafted GeoJSON document is inserted into a collection with a 2dsphere index, an inconsistency in geometry parsing can leave an internal object in an invalid, partially initialized state. During subsequent index key generation, access to this improperly initialized object results in a null pointer dereference that terminates the mongod process. An authenticated user with write access can use this to cause a denial of service.

Title
Uncontrolled Resource Consumption in MongoDB Server JSON Pointer Parser Leads to Denial of Service
Summary
A security issue exists in MongoDB server's JSON Pointer parser used during $jsonSchema query filter processing. When a find command includes a specially crafted $jsonSchema filter field, the parser processes the input without enforcing adequate limits on iteration count or total allocation size, resulting in significant memory amplification. Under concurrent request load, the cumulative memory consumption can exhaust available heap memory, causing the server's out-of-memory handler to terminate the mongod process and deny service to all connected clients.

Title
Improper Session Handling in MongoDB Server LDAP Authorization Integration Leads to Incorrect Role Assignment
Summary
A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can retain stale authentication identities after user authentication under certain configurations. Subsequent authorization queries may execute under an unintended LDAP identity rather than the expected one. This can result in incorrect role assignments based on the LDAP directory's access control configuration, potentially allowing an authenticated user to acquire elevated privileges that were not intended by the deployment's authorization policy.

Title
Race Condition in MongoDB Server Document Value Layer Leads to Memory Corruption
Summary
A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.

Title
Integer Overflow in Query Planner Leads to Unbounded Memory Allocation and Denial of Service in MongoDB Server
Summary
An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.

Title
MongoDB v8.3.0 Heap Buffer Underflow in OpenLDAP LMDB mdb_load
Summary
A heap buffer underflow vulnerability exists in the readline() function of
OpenLDAP's Lightning Memory-Mapped Database (LMDB) mdb_load utility. The
vulnerability is triggered through malformed input data and results in an
out-of-bounds read one byte before an allocated heap buffer. This can lead
to information disclosure through heap memory leakage.
*Root Cause:*
The vulnerability occurs in the readline() function at line 214 of
mdb_load.c. The ASAN output reveals two critical issues:
1. *Integer Underflow:* An unsigned offset addition to 0x521000000100
results in underflow to 0x5210000000ff, indicating a pointer decrement
operation that wraps below the buffer start
2. *Out-of-bounds Read: *The subsequent memory access reads 1 byte at
address 0x5210000000ff, which is located 1 byte before the 4096-byte heap
region [0x521000000100, 0x521000001100)
*Impact:*
The vulnerability allows a local attacker to trigger a heap out-of-bounds
read in mdb_load, resulting in reliable denial of service and limited
information disclosure of adjacent heap memory. While no write primitive is
present, the disclosure may expose heap metadata and contribute to exploit
mitigation bypass in multi-stage attacks.
*Evidence:*
# Execute with crash input
./mdb_load -T /tmp/lmdb_asan < [crash_input_file]
*Output:*
mdb_load.c:214:9: runtime error: addition of unsigned offset to
0x521000000100 overflowed to 0x5210000000ff

Title
MongoDB v8.3.0 Integer Underflow in LMDB mdb_load
Summary
This integer underflow vulnerability enables heap metadata corruption and
information disclosure through carefully crafted LMDB dump files.
*Impact:*
- *Denial of Service*: Immediate crash (confirmed)
- *Information Disclosure*: Heap metadata leak via OOB read
Root Cause:The readline() function fails to validate that the input line
length is non-zero before performing decrement operations, causing integer
underflow. An attacker can craft a malicious LMDB dump file containing
empty lines that trigger the vulnerability when processed by mdb_load:
*Output:*
./mdb_load -T /tmp/lmdb_asan <
/root/wiredtiger/third_party/openldap_liblmdb/findings/default/crashes/id:000007,sig:06,src:000012+000030,time:43032,execs:522id:000007,sig:06,src:000012+000030,time:43032,execs:52230,op:splice,rep:13
mdb_load.c:214:9: runtime error: addition of unsigned offset to
0x521000000100 overflowed to 0x5210000000ff
