My System is now patched - MongoBleed (CVE-2025-14847)

I want to share a critical update regarding server security. Recently, a major vulnerability known as MongoBleed (CVE-2025-14847) https://nvd.nist.gov/vuln/detail/CVE-2025-14847 was discovered. This is a severe memory leak issue that allows unauthenticated attackers to read sensitive data directly from a server's memory.

The Risk: Seeing What’s Not Meant to be Seen
To understand the impact, I tested the exploit on one of my non-public unpatched server which runs the version 6.0.26 of Mongo. The results were alarming: the scan easily leaked internal database names and specific smartcontract details (as seen in the image). In a production environment, this could expose private keys, session tokens, or just other sensitive user data. (Not the case for HIVE ENGINE - since there are no Keys etc. stored in the Database)

You can find more technical details and the exploit script for the POC on GitHub here made by Joe Desimone 👉 https://github.com/joe-desimone/mongobleed

How to Check Your Version

You should immediately check which version of MongoDB you are running. Open your terminal and type: mongod --version

Affected Versions

The Fix: Secure Versions

The vulnerability is fixed in the latest patch releases. To be safe, you must be on at least one of these versions:

• Series 8.2.x: Update to 8.2.3 or higher
• Series 8.0.x: Update to 8.0.17 or higher
• Series 7.0.x: Update to 7.0.28 or higher
• Series 6.0.x: Update to 6.0.27 or higher (I am now running 6.0.27)
• Series 5.0.x: Update to 5.0.32 or higher

I have successfully updated my node to v6.0.27. My Hive-Smart-Contracts are running good, and the memory leak is now closed.

If you are running your own nodes... especially for Hive or other blockchain infrastructure... please update immediately.
Stay secure!

PS: Technical Note - The MongoBleed exploit specifically targets a vulnerability in the zlib compression. While some suggest disabling compression as a quick fix, this is only a temporary workaround. Updating to version 6.0.27 in my case and you at your next secure version is the only "clean" and permanent solution to ensure your server remains both performant and secure.
