BIT-MONGODB-2026-13078 Local File Disclosure in MongoDB Server via MozJS Scripting Engine Module Loader

A vulnerability was discovered in MongoDB Server where the server-side MozJS scripting engine unconditionally registered a module loading hook that enables JavaScript calls to read arbitrary files from the host filesystem using the mongod process's privileges. An authenticated user could exploit...

BIT-MONGODB-2026-13077 Out-of-Bounds Heap Read in BSON CodeWScope Element Parsing via Malformed BSONColumn Data

A missing bounds check in the BSON CodeWScope element accessors allows an attacker to trigger an out-of-bounds heap read via a crafted aggregation pipeline. The vulnerability can be exploited by an authenticated user by generating a malformed BSONColumn data containing a CodeWScope element,...

BIT-MONGODB-2026-13075 $rankFusion and $scoreFusion Unbounded Memory Allocation During Error Suggestion Generation

An authenticated user can cause the mongod process to be terminated by the operating system under memory pressure via the $rankFusion and $scoreFusion aggregation stages. The issue originates in the server's error-handling path and requires the ability to run aggregation queries...

BIT-MONGODB-2026-13072 MongoDB Improper Input Validation in Compute Mode External Data Processing Leading to Memory Corruption

When compute mode is enabled on a standalone mongod instance, insufficient validation of externally sourced BSON data during aggregation pipeline processing can result in memory corruption, potentially leading to process termination or other unintended behavior. This configuration is non-default...

BIT-MONGODB-2026-13057 Authorization Bypass via Client-Supplied $search.mergingPipeline Leaks Unauthorized Collection Data Through $$SEARCH_META

An issue in the server’s Atlas Search integration allows an authenticated user to bypass per-user access controls. In sharded topologies, the $search and $searchMeta aggregation stages use internal routing that is normally populated only by the trusted router during sharded search planning. Due t...
