Insufficient Validation of Storage Engine Configuration Options in MongoDB Server Leads to Out-of-Bounds Write

Published Sep 8, 2026 · Updated Sep 8, 2026 · Assigned by mongodb

Description

Insufficient validation of storage engine configuration options in MongoDB Server allows an authenticated user with write privileges to supply crafted parameters during collection creation that override internal storage metadata. This results in an out-of-bounds memory write in the server process, causing a denial of service via server crash, with potential for further impact including arbitrary code execution.
