MongoDB Server: resource exhaustion
High7.1CVE-2026-13076 · Published Jul 22, 2026 · updated Aug 18, 2026
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.
