A critical security flaw dubbed "MongoBleed" is threatening over 87,000 MongoDB databases exposed online. The vulnerability (CVE-2025-14847) allows unauthenticated attackers to steal sensitive data directly from database memory, including passwords, session tokens, and customer information. The flaw exploits MongoDB's default zlib compression feature. When attackers send specially crafted packets, they can "bleed" memory contents without needing login credentials. A proof-of-concept exploit is already public on GitHub, dramatically increasing attack risks. Affected versions span from legacy 3.6 to current 8.2 releases. MongoDB has released patches, and administrators should immediately upgrade to versions 8.2.3, 8.0.17, 7.0.28, or newer. Organizations can temporarily disable zlib compression as a stopgap measure. **Source:** [Cybersecurity News](https://cybersecuritynews.com/mongobleed/)
