Global MongoDB vulnerability raises alarms as 87,000 potentially susceptible instances identified worldwide, with experts warning of critical implications for organizations relying on the database management solution. Stay up-to-date on the latest developments and learn how to protect your organization's sensitive data from this emerging threat.
There is a critical security vulnerability in MongoDB known as CVE-2025-14847. The vulnerability, codenamed "MongoBleed," allows an unauthenticated attacker to remotely leak sensitive data from the MongoDB server memory. Over 87,000 potentially susceptible instances of MongoDB have been identified across the globe. The root cause lies in a flaw in zlib compression that can be exploited by sending malformed network packets. Patches are available for affected versions, and temporary workarounds can also be implemented to disable zlib compression. Organizations must take immediate action to update their MongoDB versions, implement additional security protocols, and monitor their databases for suspicious activity.
In a recent and alarming development, a security vulnerability in MongoDB has been discovered, prompting widespread concern among cybersecurity experts and users alike. The vulnerability, known as CVE-2025-14847, is being actively exploited in the wild, with over 87,000 potentially susceptible instances identified across the globe.
The root cause of this critical issue lies in a flaw in zlib compression, which allows an unauthenticated attacker to remotely leak sensitive data from the MongoDB server memory. This vulnerability, codenamed "MongoBleed," has far-reaching implications for organizations that rely on MongoDB as their primary database management solution. According to OX Security, the attackers exploiting this weakness can trigger information leakage by sending malformed network packets, which can lead to the extraction of sensitive information such as user data, passwords, and API keys.
The problem is rooted in the zlib message decompression implementation in MongoDB Server's "message_compressor_zlib.cpp" module. This vulnerability affects instances with zlib compression enabled, which is the default configuration. As a result, even organizations that have taken precautions to secure their databases are not immune to this threat. In fact, security researchers Merav Bar and Amitai Cohen noted that the affected logic returned the allocated buffer size (output.length()) instead of the actual decompressed data length, allowing undersized or malformed payloads to expose adjacent heap memory.
The severity of this issue cannot be overstated, with Cloud security company Wiz warning that 42% of cloud environments have at least one instance of MongoDB in a version vulnerable to CVE-2025-14847. This includes both internet-exposed and internal resources, making it essential for organizations to take immediate action to protect themselves.
In response to this critical vulnerability, MongoDB has released patches for versions 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, and 4.4.30. Additionally, Wiz noted that patches for MongoDB Atlas have been applied. As a temporary workaround, organizations 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.
In conclusion, this recent discovery highlights the importance of regular database security audits and the need for proactive measures to protect against emerging threats. Organizations must take immediate action to update their MongoDB versions, implement additional security protocols, and monitor their databases for any signs of suspicious activity. As the threat landscape continues to evolve, it is essential that organizations prioritize database security and stay vigilant in the face of emerging risks.
