Attackers are actively exploiting a critical MongoDB vulnerability dubbed "MongoBleed" that lets them steal passwords, API keys, and sensitive data directly from server memory without authentication. The attacks started December 29, just three days after exploit code went public. CVE-2025-14847 affects MongoDB versions 4.4 through 8.0 that use Zlib compression. Attackers send specially crafted network packets to trick servers into leaking memory contents. While they can't target specific data, repeated attempts can capture valuable secrets from concurrent database sessions. MongoDB rates this 8.7/10 severity, but security firm Rapid7 calls it critical. A new GUI tool now makes exploitation easier for less skilled attackers. Organizations should immediately upgrade to patched versions or disable Zlib compression as a temporary fix. **Source:** [Dark Reading](https://www.darkreading.com/cloud-security/mongobleed-bug-active-attack-patch)
