CVE-2025-3084Network attack vector

Authenticated router crash via unvalidated explain arguments

Published Apr 1, 2025 · Updated Apr 1, 2025

Improper argument validation in MongoDB Server allows remote authenticated users to crash router servers through an explain command. The explain path uses certain command arguments without validating them, causing exceptional input to terminate the mongos router process. A user must have authenticated database access and submit an affected command; the reported impact is a router crash without data disclosure or modification.
