MongoDB and MongoDB Server Improper Handling of Length Parameter Inconsistency Vulnerability

Mismatched length fields in Zlib compressed protocol headers may allow a read of uninitialized heap memory by an unauthenticated client. This issue affects all MongoDB Server v7.0 prior to 7.0.28 versions, MongoDB Server v8.0 versions prior to 8.0.17, MongoDB Server v8.2 versions prior to 8.2.3, MongoDB Server v6.0 versions prior to 6.0.27, MongoDB Server v5.0 versions prior to 5.0.32, MongoDB Server v4.4 versions prior to 4.4.30, MongoDB Server v4.2 versions greater than or equal to 4.2.0, MongoDB Server v4.0 versions greater than or equal to 4.0.0, and MongoDB Server v3.6 versions greater than or equal to 3.6.0.

CVE-2025-14345 Média · 5.4 CWE-667 09/12/2025

Cross-Shard Failovers May Lead to Partial Transaction Commit in MongoDB Server

A post-authentication flaw in the network two-phase commit protocol used for cross-shard transactions in MongoDB Server may lead to logical data inconsistencies under specific conditions which are not predictable and exist for a very short period of time. This error can cause the transaction coordination logic to misinterpret the transaction as committed, resulting in inconsistent state on those shards. This may lead to low integrity and availability impact. This issue impacts MongoDB Server v8.0 versions prior to 8.0.16, MongoDB Server v7.0 versions prior to 7.0.26 and MongoDB server v8.2 versions prior to 8.2.2.

CVE-2025-13644 Alta · 7.5 CWE-617 25/11/2025

MongoDB may be susceptible to Invariant Failure due to batched delete

MongoDB Server may experience an invariant failure during batched delete operations when handling documents. The issue arises when the server mistakenly assumes the presence of multiple documents in a batch based solely on document size exceeding BSONObjMaxSize. This issue affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.13, and MongoDB Server v8.1 versions prior to 8.1.2

CVE-2025-13643 Média · 6.5 CWE-862 25/11/2025

MongoDB Server may allow queries to be terminated by unauthorized users

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 fraction of queries from successfully completing. This issue affects MongoDB Server v7.0 versions prior to 7.0.26 and MongoDB Server v8.0 versions prior to 8.0.14

CVE-2025-13507 Média · 6.5 CWE-1284 25/11/2025

Time-series operations may cause internal BSON size limit to be exceed

Inconsistent object size validation in time series processing logic may result in later processing of oversized BSON documents leading to an assert failing and process termination. This issue impacts MongoDB Server v7.0 versions prior to 7.0.26, v8.0 versions prior to 8.0.16 and MongoDB server v8.2 versions prior to 8.2.1.

CVE-2025-12893 Média · 5.4 CWE-295 25/11/2025

Improper Certificate Validation May Allow Successful TLS Handshaking Despite Invalid Extended Key Usage Fields in MongoDB Server

Clients may successfully perform a TLS handshake with a MongoDB server despite presenting a client certificate not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = clientAuth may still be successfully authenticated via the TLS handshake as a client. This issue is specific to MongoDB servers running on Windows or Apple as the expected validation behavior functions correctly on Linux systems. Additionally, MongoDB servers may successfully establish egress TLS connections with servers that present server certificates not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = serverAuth may still be successfully authenticated via the TLS handshake as a server. This issue is specific to MongoDB servers running on Apple as the expected validation behavior functions correctly on both Linux and Windows systems. This vulnerability affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.16 and MongoDB Server v8.2 versions prior to 8.2.2

CVE-2025-12657 Média · 5.5 CWE-754 03/11/2025

Malformed KMIP response may result in access violation

The KMIP response parser built into mongo binaries is overly tolerant of certain malformed packets, and may parse them into invalid objects. Later reads of this object can result in read access violations.

CVE-2025-11979 Média · 6.5 CWE-416 20/10/2025

Use-after-free in the MongoDB server query planner may lead to crash or undefined behavior

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 MongoDB Server v7.0 versions prior to 7.0.25, MongoDB Server v8.0 versions prior to 8.0.15, and MongoDB Server version 8.2.0.
