MongoDB has issued a high-priority warning about a severe remote code execution vulnerability (CVE-2025-14847) affecting multiple versions of the database management system. Organizations using MongoDB are urged to patch the issue immediately to prevent potential attacks.
A high-severity vulnerability (CVE-2025-14847) has been identified in MongoDB that could be exploited for remote code execution (RCE). The vulnerability affects multiple MongoDB and MongoDB Server versions, including those with low-complexity attacks. It can return uninitialized heap memory without authenticating to the server, making it possible for attackers to execute malicious code even if authentication fails. Disabling zlib compression on MongoDB Server may mitigate some risks, but upgrading to a fixed version of MongoDB is recommended.
A high-severity vulnerability has been identified in MongoDB that could be exploited by unauthenticated threat actors to achieve remote code execution (RCE) on vulnerable servers. The vulnerability, tracked as CVE-2025-14847, affects multiple MongoDB and MongoDB Server versions and may be exploited through low-complexity attacks that don't require user interaction.
The security flaw is due to an improper handling of length parameter inconsistency in the zlib compressed protocol header, which can allow attackers to execute arbitrary code and potentially gain control of targeted devices. This vulnerability has significant implications for organizations that use MongoDB as their database management system, particularly those with multiple servers across different locations.
In a recent advisory, MongoDB's security team warned IT administrators to immediately patch the vulnerability to prevent potential attacks. The team emphasized the severity of the issue, stating that it can return uninitialized heap memory without authenticating to the server. This means that even if an attacker is unable to authenticate to the server, they can still exploit the vulnerability to execute malicious code.
The advisory also provides guidance on how to disable zlib compression on MongoDB Server to mitigate the risk. However, this approach may not be sufficient to prevent all types of attacks, and organizations are advised to upgrade to a fixed version of MongoDB as soon as possible.
It's worth noting that the United States Cybersecurity and Infrastructure Security Agency (CISA) has added the MongoDB mongo-express RCE flaw, tracked as CVE-2019-10758, to its catalog of known exploited vulnerabilities. This vulnerability was discovered in 2019 and is not directly related to the new CVE-2025-14847.
The discovery of this vulnerability highlights the importance of regular security updates and patching of database management systems. Organizations that rely on MongoDB should take immediate action to address this vulnerability and ensure that their servers are protected against potential attacks.
In addition, the growing number of actively exploited vulnerabilities in the past year has emphasized the need for robust incident response strategies and continuous monitoring of system configurations.
