MongoDB Memory Disclosure (CVE-2025-14847) - Mongobleed

Disclosed
Dec 19, 2025

Description

This module exploits a memory disclosure vulnerability in MongoDB's zlib
decompression handling (CVE-2025-14847). By sending crafted OP_COMPRESSED
messages with inflated BSON document lengths, the server reads beyond the
decompressed buffer and returns leaked memory contents in error messages.

The vulnerability allows unauthenticated remote attackers to leak server
memory which may contain sensitive information such as credentials, session
tokens, encryption keys, or other application data.
