MongoDB has issued a high-priority alert urging its administrators to patch a severe memory-read vulnerability that may be exploited by unauthenticated attackers remotely. The vulnerability affects multiple versions of the database management system, including 8.2, 8.0, 7.0, 6.0, and 5.0. Administrators are advised to upgrade to fixed versions or disable zlib compression immediately.
MongoDB has issued a warning about a high-severity memory-read vulnerability (CVE-2025-14847) that may be exploited by unauthenticated attackers remotely. The vulnerability affects multiple MongoDB and MongoDB Server versions, including recent ones like MongoDB 8.2.0 through 8.2.3. The flaw is related to an improper handling of length parameter inconsistency in the zlib implementation of the server. Administrators are advised to upgrade to a fixed version or disable zlib compression on their MongoDB Server as soon as possible.
MongoDB has issued a warning to its administrators, urging them to patch a high-severity memory-read vulnerability that may be exploited by unauthenticated attackers remotely. The vulnerability, tracked as CVE-2025-14847, affects multiple MongoDB and MongoDB Server versions and may be abused in low-complexity attacks that don't require user interaction.
The security flaw is related to an improper handling of length parameter inconsistency in the zlib implementation of the server. This can return uninitialized heap memory without authenticating to the server, allowing unauthenticated attackers to potentially execute arbitrary code and gain control of targeted devices in some cases. However, it's essential to note that the vulnerability has not been officially classified as a Remote Code Execution (RCE) attack.
According to MongoDB's security team, the company strongly recommends upgrading to a fixed version of the server as soon as possible. If immediate upgrades are not feasible, administrators can disable zlib compression on the MongoDB Server by starting mongod or mongos with a networkMessageCompressors or a net.compression.compressors option that explicitly omits zlib.
The vulnerability impacts various MongoDB versions, including:
- MongoDB 8.2.0 through 8.2.3
- MongoDB 8.0.0 through 8.0.16
- MongoDB 7.0.0 through 7.0.26
- MongoDB 6.0.0 through 6.0.26
- MongoDB 5.0.0 through 5.0.31
- MongoDB 4.4.0 through 4.4.29
All versions of MongoDB Server v4.2, v4.0, and v3.6 are also affected.
In addition to the recent warning from MongoDB, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has previously added a MongoDB mongo-express RCE flaw (CVE-2019-10758) to its catalog of known exploited vulnerabilities, highlighting the importance of proactive security measures in protecting against such threats.
MongoDB is a popular non-relational database management system that stores data in BSON (Binary JSON) documents instead of tables. The company has implemented several security measures to ensure the integrity and reliability of its services, including regular updates and patches for identified vulnerabilities.
As organizations rely on MongoDB to store and manage their critical data, it's essential for them to stay vigilant and proactive in addressing potential security threats. In light of this recent warning, administrators are advised to take immediate action to patch the vulnerability and ensure the security of their MongoDB servers.
