Improper Validation in MongoDB Queryable Encryption Maintenance Operation Leads to Denial of Service and Index Corruption

view advisory published 2026-09-17Licence: per source

MongoDB Server's handling of a Queryable Encryption maintenance operation did not properly validate certain request parameters against the collection's encrypted field configuration before use. An authenticated user with readWrite privileges could submit a specially formed request that leads to a server crash or excessive internal writes, resulting in resource exhaustion and corruption of encrypted index data.
