Critical MongoDB Vulnerability Exposes Sensitive Data via Zlib Compression

**CVE-2025-14847** — A critical unauthenticated vulnerability in MongoDB's zlib compression can allow remote clients to extract uninitialized heap memory and potentially disclose sensitive data (including cryptographic keys) across many MongoDB releases; MongoDB advises immediate upgrade to specified patched versions (e.g., 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32, 4.4.30) or temporarily disable zlib compression and use alternatives like Snappy or Zstd.
