Aggregation Framework Memory Exhaustion Leading to Process Termination
CVE-2026-13076 is fixed in MongoDB on 1 platform by MongoDB 8.3.7 (version 8.3.7), released June 11, 2026. It is not reported as exploited. Patch Radar priority: High.
An authenticated user can cause a {{mongod}} process to be terminated by the operating system under memory pressure by performing a specific data type conversion operation within MongoDB's aggregation framework. The behavior stems from disproportionate memory consumption during this operation, and requires both write access to the database and the ability to run aggregation queries.
