A critical flaw in the popular open-source NoSQL database MongoDB could be exploited by attackers to take over vulnerable servers, giving them access to sensitive data. The high-severity vulnerability has been rated at 8.7 on the Common Vulnerability Scoring System (CVSS) and affects various versions of the database software. Users are advised to upgrade to a fixed version or configure compression options to mitigate this risk.
A high-severity vulnerability (CVE-2025-14847) has been identified in MongoDB, allowing remote code execution on vulnerable servers. The vulnerability affects various versions of the database software, including 8.2.0 through 8.2.3 and older versions like 7.0.0 through 7.0.26. The severity of this vulnerability is rated at 8.7 on the Common Vulnerability Scoring System (CVSS). The exploit relies on a client-side attack targeting zlib implementation, allowing attackers to execute arbitrary code without authenticating. Upgrading to a fixed version or disabling zlib compression can mitigate this risk.
A high-severity vulnerability has been identified in MongoDB, a popular open-source NoSQL database used by many organizations around the world. The vulnerability, tracked as CVE-2025-14847, could potentially be exploited to achieve remote code execution on vulnerable servers, giving attackers unprecedented access to sensitive data.
According to a recent advisory issued by MongoDB, the vulnerability affects various versions of the database software, including MongoDB 8.2.0 through 8.2.3, MongoDB 8.0.0 through 8.0.16, and even older versions such as MongoDB 7.0.0 through 7.0.26, among others. The severity of this vulnerability has been rated at 8.7 on the Common Vulnerability Scoring System (CVSS), which is considered to be one of the most critical levels of vulnerability.
The exploit of this vulnerability relies on a client-side attack that targets the Server's zlib implementation, allowing an attacker to return uninitialized heap memory without authenticating to the server. This means that even if a user logs in to the database with valid credentials, they may still be able to execute arbitrary code on the vulnerable server.
In order to mitigate this risk, MongoDB has recommended upgrading to a fixed version of the software as soon as possible. However, for organizations that are unable to upgrade immediately, there is an alternative solution: disabling zlib compression on MongoDB by configuring compression options to omit zlib.
This vulnerability highlights the importance of keeping software up-to-date and taking proactive measures to prevent exploitation of known vulnerabilities. In this case, it may not be enough to simply keep the database software patched; users must also take steps to configure their systems properly to avoid falling victim to an attack.
The impact of this vulnerability is significant, given that MongoDB is widely used in many industries and organizations. It is essential for users to act quickly to address this issue and prevent potential attacks.
