Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices.
This issue affects MongoDB Server v7.0 versions prior to 7.0.32, v8.0 versions prior to 8.0.21 and v8.2 versions prior to 8.2.6
AnalysisAI
Denial of service in MongoDB Server 7.0, 8.0, and 8.2 allows authenticated remote attackers to crash the database by inserting documents that trigger updates to a maliciously created '2dsphere_bucket' or 'queryable_encrypted_range' index on a non-timeseries bucket collection. The flaw stems from a reachable assertion (CWE-617) and is reported by MongoDB itself with a vendor patch available; no public exploit identified at time of analysis.

RemediationAI
Within 24 hours: inventory all MongoDB Server instances (versions 7.0, 8.0, 8.2) and document user access levels. Within 7 days: apply the vendor-released security patch to all affected instances; alternatively, restrict database access to essential applications only if patching cannot be completed immediately. …
