Lifecycle Timeline
3DescriptionCVE.org
A security issue in the MongoDB Server's storage engine integration layer allows an authenticated user with collection creation privileges to cause a persistent denial of service. Insufficient validation of user-supplied storage configuration options permits values that, once persisted to durable metadata, trigger a fatal assertion failure when the metadata is subsequently read by diagnostic operations. The corrupted metadata persists across server restarts and is replicated to other cluster members, requiring manual operator intervention to restore service.

AnalysisAI
Persistent denial-of-service in MongoDB Server (versions 7.0.x, 8.0.x, and 8.3.x) allows an authenticated user with collection creation privileges to corrupt durable storage metadata by supplying invalid storage configuration options that bypass validation in the storage engine integration layer. The malformed values are written to disk and trigger a fatal CWE-617 assertion failure when subsequent diagnostic operations attempt to read them back, crashing the server process. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated MongoDB user account possessing the createCollection privilege, which is granted by standard roles such as readWrite, dbAdmin, or dbOwner on the target database. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VA:H, score 7.1) captures a network-exploitable, low-complexity flaw with high availability impact gated behind low-privilege authentication. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade MongoDB Server to one of the vendor-released patched builds: 7.0.41 for the 7.0.x train, 8.0.30 for the 8.0.x train, or 8.3.9 for the 8.3.x train, as confirmed by the EUVD-2026-72952 version ranges. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all MongoDB instances running versions 7.0.x, 8.0.x, or 8.3.x in production and audit user accounts holding collection creation privileges; revoke collection creation permissions from all non-essential accounts immediately. …
