CVE-2025-14847, nicknamed MongoBleed, is a high-severity (CVSS 7.5–8.7) unauthenticated information disclosure vulnerability in MongoDB Server. It allows remote attackers to leak uninitialized heap memory containing sensitive data—such as credentials, API keys, session tokens, and PII—without authentication. Exploitation occurs pre-authentication via malformed zlib-compressed network packets on port 27017.

On December 19, 2025, MongoDB issued an advisory for CVE-2025-14847, known as “MongoBleed,” a high-severity vulnerability in the server’s zlib-based network compression functionality. This vulnerability affects how the database handles compressed network communications and can cause it to accidentally leak sensitive information from its memory when abused by unauthenticated threat actors. The problem occurs when MongoDB receives a specially crafted message.

A newly disclosed MongoDB vulnerability, tracked as CVE-2025-14847 and informally referred to as MongoBleed, allows unauthenticated remote attackers to leak uninitialized memory from a MongoDB server. A public proof-of-concept exploit is already available, significantly increasing the risk for exposed MongoDB deployments. This post explains how the vulnerability works, what is required to exploit it, and how ARMO helps identify exposure and detect exploitation attempts at runtime.

In the world of database security, few things are as alarming as an unauthenticated memory leak. It recalls the panic of OpenSSL’s Heartbleed - a vulnerability where a simple heartbeat request could bleed out sensitive secrets from a server's memory. Now, MongoDB users are facing their own version: CVE-2025-14847, widely dubbed "MongoBleed".

A database-as-a-service (DBaaS) product eliminates the complexity of managing database infrastructure while reducing operational costs by up to 40%. Organizations can provision, configure, and scale databases instantly without hardware maintenance or software updates. MariaDB’s recent SkySQL reacquisition highlights the market shift toward flexible deployment models that support self-managed, hybrid, and fully managed environments.

If you've ever been involved in a major database migration, you know just how complex and honestly, nerve-wracking they can be. At Tines, we recently faced the challenge of migrating a customer's dedicated tenant by moving all the customer’s critical workloads running on Tines between two different AWS Regions. All while maintaining 100% system availability.

Losing a MySQL database without a backup means losing customer records, transactions, and your business’s good reputation. Whether you’re running a single application or managing containerized workloads, you need a backup strategy that works when disaster strikes. The challenge isn’t just creating backups but making sure that they’re consistent, they’re recoverable, and they match your recovery time objectives.
