MongoBleed: The MongoDB Security Flaw That’s Making Data Leak Like a Sieve!
MongoBleed is here to swipe your data faster than you can say “zlib compression.” This MongoDB vulnerability, CVE-2025-14847, lets hackers eavesdrop on sensitive server memory like it’s the latest podcast. With over 87,000 instances on the line, it’s time to update your MongoDB and reconsider your love for zlib compression. Stay safe, folks!

Hot Take:
MongoDB, the database that could, just went from being a data sponge to a data sieve. With “MongoBleed” knocking on its door, it’s time for servers around the world to patch up those memory leaks or risk spilling the beans—or rather, the bytes—of sensitive data to anyone who asks nicely (or not so nicely). In other words, it’s like your database just forgot how to keep a secret!
Key Points:
- MongoDB’s latest vulnerability, CVE-2025-14847, has a CVSS score of 8.7 and is codenamed “MongoBleed”.
