On December 19, 2025, MongoDB Inc. disclosed a critical new vulnerability, CVE-2025-14847, which has since been dubbed MongoBleed. This vulnerability is a high-severity unauthenticated memory leak affecting MongoDB, one of the world’s most popular document-oriented databases. While initially identified as a data exposure flaw, the severity is underscored by the fact that it allows attackers to bypass authentication entirely to extract sensitive information directly from server memory. On December 26, 2025, public proof-of-concept (PoC) exploit code was published and on December 29th, 2025 exploitation in-the-wild has been confirmed.
While CVE-2025-14847 is rated as a high-severity vulnerability, CVSS 8.7, its impact is critical. Successful exploitation allows a remote, unauthenticated attacker to “bleed” uninitialized heap memory from the database server by manipulating Zlib-compressed network packets.
