MongoDB Server contains an incorrect authorization vulnerability in the aggregation framework. An authenticated user with minimal privileges can craft a specially formatted aggregation request that causes the server's authorization subsystem to evaluate a different operation than what is actually executed, resulting in unauthorized read access to collection data within the target database.

AnalysisAI
Incorrect authorization in MongoDB Server's aggregation framework allows an authenticated low-privilege user to craft a specially formatted aggregation request that causes the authorization subsystem to evaluate a different operation than what the execution engine actually runs, resulting in unauthorized read access to collection data within the target database. Affected versions span MongoDB Server 7.0.0-7.0.40 and 8.0.0-8.0.29; vendor-released patches are available at 7.0.41 and 8.0.30 respectively. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid MongoDB account with at minimum a low-privilege role providing some form of access within the target database - for example, a read-only grant on any single collection. … 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/VC:H/VI:N/VA:N) reflects a network-accessible, low-complexity vulnerability requiring only low privileges, with high confidentiality impact and no integrity or availability impact; the resulting score of 7.1 (High) is consistent with the described behavior. … 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 version 7.0.41 or later on the 7.0.x branch, or to 8.0.30 or later on the 8.0.x branch; vendor patch availability is confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all MongoDB Server instances running versions 7.0.0-7.0.40 or 8.0.0-8.0.29 across development, staging, and production environments. …
