Lifecycle Timeline
4DescriptionCVE.org
A user with access to the cluster with a limited set of privilege actions can trigger a crash of a mongod process during the limited and unpredictable window when the cluster is being promoted from a replica set to a sharded cluster. This may cause a denial of service by taking down the primary of the replica set.
This issue affects MongoDB Server v8.2 versions prior to 8.2.2, MongoDB Server v8.0 versions between 8.0.18, MongoDB Server v7.0 versions between 7.0.31.
AnalysisAI
Denial of service in MongoDB Server allows authenticated users with limited cluster privileges to crash a mongod process during replica set to sharded cluster promotion, causing potential primary failure. Affects MongoDB 8.2 before 8.2.2, 8.0.18+, and 7.0.31+. …

Vulnerability AssessmentAI
| Risk Assessment | The CVSS score of 5.3 reflects medium-low severity with important contextual factors: the attack vector is network-based (AV:N), but the attack complexity is high (AC:H) due to the narrow and unpredictable window for exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated operator with limited cluster administration privileges monitors upcoming scheduled maintenance for cluster topology changes. When a replica set begins promotion to sharded cluster, the operator with knowledge of this timing window submits a crafted request to the primary mongod during the vulnerable transition phase. … |
| Remediation | MongoDB users should upgrade to patched versions: MongoDB Server 8.2.2 or later, a patched 8.0.x version (8.0.19 or later based on standard MongoDB versioning), and a patched 7.0.x version (7.0.32 or later). … Detailed patch versions, workarounds, and compensating controls in full report. |
